Android Emulator closed because of an internal error: GPU Found

I haven't been on Android Studios in a number of days. When I went back on my emulator kept getting killed. I deleted all my emulators and the AVD manager folder in .android. After selecting that the emulator graphics be Software GLES 2.0 the emulator works and can run the application but it is very, very slow. Only a week ago the emualtor and Android Studios worked great.
I am receiving this error messaging now after re-installing an emulator with API level 28 (Pie):

Answer that work [28. July 2021]
First of all update your graphic card with the latest driver. (Graphic Card Model can be checked through your Device Manager)
Type in your explorer the following path, where <pc_name> need to be replaced with your individual name:
C:\Users<pc_name>.android
In the above mentioned directory we will put a .ini file that I prepared and is ready to download here. This file will disable your Vulkan driver and enable your GLDirect driver that your AVDs don't lag anymore. (watch image below)
Start your AVD and you will be able to use it without any troubles.

There is a missing or corrupted file amdvlk64.dll.I fixed this by given steps.
Download amdvlk64.dll from This Link , this is for 64 bit OS, you can search fro 32 bit also.
After Download, extract the folder on your desktop.
Open Extracted folder and Copy the amdvlk64.dll file.
Now Paste this file in C:\Windows\System32
Again run the emulator, hopefully it will run.

In my case I resolved this by performing the pending SDK Tools updates in the SDK Manager.

I get this error (Emulator is closed because of internal error: gpu found)
suddenly while I am running my code. So how I solve the problem is,
Go to AVD Manager or (Virtual Device Manager).
Edit your AVD or (Virtual Device Manager).
Select 'Software GLES2.0' option on Emulated Performance.
Click Finish.
Start AVD again

Download and install this vulkan-dll driver.
There are those who think that the comment I added is a virus, I researched the subject a lot and finally reached the address, almost 48 hours later, so I installed my emulator, my aim is just to help.

For me, the same error showed even though I have NVIDIA GPU.
Restarting the system after the NVIDIA driver update fixed the problem.

I installed Android studio in Windows 10(AMD Ryzen), the following one helped me to run the emulator smoothly. Once you installed Virtual device from AVD manager successfully, then your emulator will popup the above error like Android emulator closed....amdvlk64.dll not found and amdvlk32.dll not found.... when you try to run your code. Just follow this steps to avoid those error, hope it works:
Close your Android studio and also emulator error popup. Go to
Control Panel.
Select Programs --> Programs and Features --> Turn windows feature
on or off (which lies in the extreme right side of the screen).
A popup appears, in that check the Windows Hypervisor Platform and
Virtual Machine Platform, then click Ok.
It ask you to restart your system, allow to restart.
After restart, now open Android studio and run your emulator, hope it will
run smoothly.

At times the error might be caused by the wrong system date/time set on your computer. Try updating the system date/time and restart the android emulator. In my case it was caused by the wrong system date/time.

is it possible to run android emulator on client's virtual machine?

We are working remotely on client's virtual machine. I keep getting the VT-X/disabling hyper-V error even after doing the needful.
So, my question is , is it possible to run emulator, which is itself a VM on another VM?
If not, suggest a way to work around this problem.
Thanks in advance

is it possible to run android emulator on client's virtual machine?
I think the problem is not you are working remotely on client's virtual machine, the problem is that your Physical machines turn on the Windows feature : Hyper-V, but when you run an Android Emulator, it needs to disabling the Hyper-V, so it gives the VT-X/disabling hyper-V error.
I have test working remotely on client's virtual machine and turn on the Hyper-V. When I run an Android emulator from Android Studio, it failed and gives me the error message :
To solve this problem, you should turn off your hyper-v and restart the computer. If you cant do this, you could try using Visual Studio Emulator for Android. As the document said :
with Hyper-V compatibility you can run the emulator side-by-side with the Windows Phone Emulator and other Hyper-V VMs
Then, you could run the Android emulator.

I don't know about what happens in a VM.
But, emulator is not possible in nested VM. I found that out while installing android studio when I got the error message explaining the same.
Regarding working emulator with VM, we can go with #Grace Feng

Unable to deploy or run emulators on Xamarin on Visual Studio 2015

I am running into a somewhat odd problem. I googled a bit, and I found a few people with similar problems but none of the solutions suggested worked for me.
Here is one though I did not check the log this guy is presenting. This is another seemingly similar issue.
I am following this Xamarin Quick Start guide for Android. The solution builds just fine. I managed to follow all the steps.
However, once I try to debug, by clicking the giant green Play button in Visual Studio, it tells me it could not Deploy the solution, with a small message on the status bar that "Deploy failed".
I tried the following solutions:
I updated Xamarin to the latest version.
I ran Visual Studio with admin rights
I updated the Android SDK to version 24, revision 5.
Even though the template project does not seem to have any NuGet packages, I checked if there is anything there that needs updating.
Downloaded and installed Intel HAXM both separately (via a link from Xamarin's website) and from the Android SDK manager.
I made sure the Android SDK Path in the Registry is the same as the one in Visual Studio, by editing the one in Visual Studio. However, when I did that the "custom" names for emulators dissapeared and were replaced with the "Start" word. Even when I created new Android Virtual Devices, the word "Start" remained. Clicking it still gives me the same error.
Yet the issue persists.
I have not tried debugging on actual Android devices as .. em .. I don't have one.
At first I came across error IDE0006 , both in the standalone Xamarin.Android app and in another Xamarin.Forms portable app. After updating stuff the error disappeared, and the deploy simply fails without errors, without even launching the emulator.
After making sure Xamarin and the Registry are pointing to the same folder for the Android SDK (by editing it in Xamarin) all the AVD definitions simply were replaced by weird question marks. I deleted them and defined one of my own, and tried to start it. It never started and it showed this:
Starting emulator for AVD 'My_AVD'
emulator: WARNING: VM heap size set below hardware specified minimum of 384MB
emulator: WARNING: Setting VM heap size to 512MB
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: VT feature disabled in BIOS/UEFI
So what did I miss? Or rather, what do I need to do?
Edit:
Enabled Intel Virtualization in BIOS as well. Now the emulators are started from the emulator manager (albeit without showing anything) but Visual Studio still cannot see them nor launch them.
Screenshots:
This is my Visual Studio window and what it shows.
And here is my Android Virtual Device Manager. Neither of these two is showing in Visual Studio at the moment.
Visual Studio cannot see any of the AVDs, period.

You missed to add the Emulator Accelerator (Haxm installer) , so facing issue to start the emulator.

Loading issue of Visual Studio Emulator for Android

I am working on an android application in VMware. I am using Visual Studio Emulator for testing. But it is not loading. It shows an error that 'one of the HyperV component not running'. I already turn on HyperV.
Attached the error alert message below.
Please help me to find a solution.
Error alert message

Please check the following answer.
You need to allow nested running of one virtual machine (Hyper-V) inside the other (VMWare)

Android Studio emulator appears in the task manager for 10 seconds and disappears. The emulator window is never displayed

It was working fine till I updated the Android SDK tools from the SDK Manager to version 24.1.2. However a virtual device was running at the time of the update and it asked me to close 3 processes in order for the update to continue. I thought the virtual device was interfering so I closed it and tried to proceed with the update,it gave me the same error. Therefore I cancelled the update and closed the studio. After restarting the studio,it gave an error saying the SDK could not be found and would not let me do anything else. I uninstalled the studio after deleting the SDK folder and reinstalled it. I downloaded the system images needed for the virtual devices and some other packages and created a new virtual device. When I tried to run the application,it gave me the dialogue box to chose the virtual device,I chose the newly created one and it gave the command to start the device. Yet no emulator window for the device appeared.
D:\sdk\tools\emulator.exe -netdelay none -netspeed full -avd MTK
emulator: device fd:5500
HAX is working and emulator runs in fast virt mode
HAXM is installed and it worked fine before. On checking the task manager upon launching the application,an emulator-x86.exe process appears briefly before disappearing. Nothing happens after that. Launching the program again gives the same result. If I try to launch the device from the AVD manager,I get the same result. I have tried using the arm images,varying the ram size,snapshot enabled/disabled,use HOST GPU enabled/disabled,system restarted,removal of /.android content,setting up the SDK in a different drive and deleting the ANDROID_SDK_HOME system variable and resetting it.
I have also tried with Genymotion. The virtual device window briefly appears and I can the see the android logo at startup but then it says "player.exe has encountered a problem and needs to close. We are sorry for the inconvenience." I have tried it using both the Genymotion Android SDK tools and the custom Android SDK tools to no avail. If I try to delete the device it says please stop the virtual device before deleting it even though it is not running.

I spent most of my day trying to solve exactly the same problem until one of my colleagues remembered he had exactly the same issue and that was related to Docker.
Docker uses Hypervisor Framework which is incompatible with the HAXM used by the Android emulator. Therefore if you try to run the Android emulator while Docker is running it will just quit without a warning. Quitting Docker will allow to use the simulator - Docker for Mac conflict with Android emulator

Sometimes it is because you are low on memory, or it might be an AVD specific glitch. I had many (20) devices saved in my AVD and was lower than normal on memory on my laptop. The native emulator folder would disappear right away but genymotion worked fine.
I removed the old devices and create a new one from scratch in AVD and the problem disappeared.
