Cannot launch Device "The emulators process for AVD Nexus_6_API_28 has terminated"

I had a problem with Android Studio.
Cannot launch emulator, the error is: "The emulators process for AVD Nexus_6_API_28 has terminated"
For better diagnostic, I desired view a log of error but cannot see anything. It´s possible for Android?
I tryed wit this post but not work:
1- Emulator: Unexpected feature list: MultiDisplay VulkanNullOptionalStrings YUV420888toNV21 YUVCache
2- Failed to launch emulator: Error: Emulator didn't connect within 60 seconds
My system is:
Android Studio Chipmunk 2021.2.1 (May 18, 2022)
Mi PC:
Intel(R) Core(TM) i7-10510U CPU # 1.80GHz 2.30 GHz
Windows 10 Pro
Any idea? Thank

In my case I was low on memory. I had 8GB of RAM and there were Google Chrome, Android Studio and few Terminals and background processes running, occupying 95% of my memory. I closed chrome and few other background processes and emulator started successfully. Sometimes I needed to restart Android Studio to run emulator.

The emulator process for AVD was killed

I just installed Android Studio and created a new AVD. However whenever I try to run it, I get an error message saying the process was killed, and the emulator will close. When running the emulator from cmd I get this message. What is going wrong?
emulator: Android emulator version 30.5.3.0 (build_id 7196367) (CL:N/A)
Warning: Quick Boot / Snapshots not supported on this machine. A CPU with EPT + UG features is currently needed. We will address this in a future release.
handleCpuAcceleration: feature check for hvf
emulator: WARNING: Not all modern X86 virtualization features supported, which introduces problems with slowdown when running Android on multicore vCPUs. Setting AVD to run with 1 vCPU core only.

Make sure you have enough space in c: drive - Minimum has 20GB free space
If you have already created AVD then go to following location in your windows machine, from command line enter "emulator -list-avds".
C:\Users\username\AppData\Local\Android\Sdk\emulator>emulator -list-avds
Pixel_2_API_29
Enter emulator #Pixel_2_API_29
C:\Users\username\AppData\Local\Android\Sdk\emulator #Pixel_2_API_29
You can see emulator launching.
It worked for me - other result found in internet didn't worked for me.

Android Studio 2.2 blank AVD & VCPU Shutdown request

I am using Android Studio 2.2 and when I try to do a trial run of hello world program, I am getting AVD with blank screen. Also In-between that the VCPU shutdown request coming in the log.I am not getting any android welcome screen after a long time (More Than 30 minutes). There is no issue with RAM performance, I already have 16gb. All the components are installed correctly from SDK. Can you help me to solve this issue? Please Find the Image below for Blank AVD AS2.2

UPDATE AFTER CHECKING WITH HAXM 6.0.5
Adding: Intel HAXM 6.0.5 not compatible with windows screenshot:

Please use 6.0.5 HAXM it solved for me. I have i7 and similar issues with 6.0.4

I just wanted to share that I am experiencing the same problem as well with my new Windows 10 computer. How do you add the switch -accel off -verbose to the x86/x64 image? Running an ARM image is extremely slow.

Dealing with the same issue. Something to do with haxm on 7th gen processors as the arm image works.
UPDATE: Confirmed to be a HAXM issue on Kaby Lake, nothing we can do until we get an HAXM update from Intel. Best workaround at this stage is to use the physical device or create a Linux partition. I haven't tested genymotion on a 7th gen processor...can anybody confirm if that works?

My AVD not working for some reason

I am trying to start the emulator in Android Studio, but for some reason it won't turn on. I've installed HAXM and invalidated caches and restarted AS but it still won't work. It is stuck at "Waiting for target device to come online". This is the response I get:
Hax is enabled
Hax ram_size 0x60000000
HAX is working and emulator runs in fast virt mode.

emulator: Serial number of this emulator (for ADB): emulator-5554
09/19 16:25:06: Launching app
Error while waiting for device: Timed out after 300seconds waiting for emulator to come online.
What else can I do?

Under Android SDK Manager you have to install Intel x86 Emulator Installer there. Android SDK Manager
check it out also:
Error in launching AVD with AMD processor

First, click on File -> Invalidate Caches/Restart.
If this solution is not working, try to update the build.gradle of your project.
For example, update the compileSdkVersion to 25, (the supports libs to 25), the buildToolsVersion 25.0.2 and the targetSdkVersion to 25. Don't forget to sync your gradle after that.

Could not open avd_name.avd/cache.img

When i run emulator, i get the following error:
Cannot launch AVD in emulator.
Output:
Hax is enabled
qemu-system-x86_64.exe: -drive if=none,index=1,id=cache,file={path_to_SDK}\SDK.android\avd{AVD_name}.avd/cache.img: could not open disk image {path_to_SDK}\SDK.android\avd{AVD_name}.avd/cache.img:

AVD specs are:
OS: Android 6.0 Google APIs
RAM: 1GB
Resolution: 1440x2560
Running on Android Studio 2.0 Beta 6, Windows 10.

Keep an eye out for a background qemu-system-i386.exe process running in the background that will be locking the cache.img file.
This might be still running from a previously failed emulator launch. Kill that using Task Manager and start again.

I had the same problem already twice since I upgraded to Android Studio 2.0 on Windows 10. I use a preferred emulator in the Run/Debug configuration. Changing the Deployment Target Options in the configuration to Target: Show Device Chooser Dialog solved it for me. After choosing the same emulator instance in the dialog it started with no problem. Then I change back to the preferred emulator setting. Until the next time it breaks...
Hoping this helps.

I faced the same problem in Windows 10.
Clearing temp and %temp% folder followed by a restart of machine solved my problem.

I had this problem, when I didn't notice that emulator is already running :)
