Android Studio crashes on start with PluginException

I am not sure whether it worked buefore, but I updated to Android Studio 4.1 today and then tried launching it, only to see the crash below.
The crash happens even when I delete everything from %appdata%\Google\AndroidStudio4.1\plugins. It seems that the problem is with the JetBrains Android plugin itself?

JRE 1.8.0_242-release-1644-b01 amd64 by JetBrains s.r.o
C:\Program Files\Android\Android Studio\jre\jre
Any help would be appreciated.

Try to go from Android Studio's start menu to Settings-Plugins and just disable and enable again all needed plugins.

Thank you for your suggestions, but I ended up simply reinstalling Android Studio. It seems that I somehow had a botched installation.

Intellij 2019 2.3 Exception in plugin Andriod Support

I need help, when on the design tab in activity_main.xml, clicking on a widget causes the error. Also the attributes panel for the widgets are blank no matter which i click and sometimes shows loading but never appears.Tried switching to the "all attributes view" but still can change any of the attributes.
Already tried to deactivate the instant run, invalidate caches, slightly older version of IntelliJ, deleting and re-downloading IntelliJ and "clean project"

I googled a lot and found some solutions like:
1) restart the computer, didn't work
2) turn off internet and then start, didn't work
3) remove .Android1.5 folder, didn't work
I'm wondering what is the solution now, I'm unable to do anything right now! If anyone has solved this issue, please let me know what is the best solutions?
System config
Ubuntu 16.04
Ram 8 GB
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

It seems like a dependency from the android-sdk could not be loaded.
This part of the error message above is ultra important:
Caused by: java.lang.NoSuchMethodError: com.android.prefs.AndroidLocation.checkAndroidSdkHome()V
I first tried to install the android sdk which did not help.
Thank I just added the ppa with:
sudo add-apt-repository ppa:maarten-fonville/android-studio
and installed android-studio with apt-get with:
sudo apt-get update
sudo apt-get install android-studio
After that it worked for me.

any idea how to fix this problem? I tried to unset Display or export Display:=0 and I did not get any solution

Fedora 25 is not using XOrg anymore by default. We moved to Wayland and Java probably does not handle that. It would be nice to report the problem to Android Studio developers (not here).
Anyway, you can workaround it by running Fedora using old X. Select the "GNOME on XOrg when logging into your account:

I got the below issue because of running as a root user. Once I exit from the root user and tried ./studio.sh it worked perfectly :)
Start Failed: Internal Error. Failed to initialize graphics environment

I got this issue because I was running as root user. This will work fine if you don't change your privilege to the super user

Now I am unable to create a new project. I follow the wizard to create a project and it finishes with creating the project, but the result is not what I expected and I get a error in the console
The error I get is:

When I try to import it does the same thing.

I must ask you for your Android Studio Build number and your system environment. But I think the following step may help. And sorry for poor English if there is any spell mistake.
Under Windows 7 x64
Android Studio 130.737825
First,check your Android Studio version . I have the problem when the version is 130.737825 . Anyway update Android Studio. "Help->Check for Update"
if it didn't work.
http://tools.android.com/recent
to check the newest Build Number or
http://dl.google.com/android/studio/patches/updates.xml
check the newest version .
Download Update package
like this one https://dl.google.com/android/studio/patches/AI-130.737825-132.821530-patch-win.jar
Please according to your own situation choose to down the right one. The format is AI-$FROM-$TO-patch-win.jar $From is the build number your Android studio. $TO is the newest build number you want to update.
Download the package to your Android Studio directory. D:\Android\android-studio.
Run cmd
D:\Android\android-studio>java -classpath AI-130.737825-132.821530-patch-win.jar com.intellij.updater.Runner install .

Moving my projects to the same partition as my Android Studio seems to have solved my problem.
Not a permanent solution but if you want to continue with your work before they fix it, you've got to do it...

I have this error, is your user folder located on a drive other than where android studio is installed?
I would've put this as a comment but can't.

I had the same issue on Win7-x64. I had put path to jdk (c:\Program Files\Java\jdk1.7.0_40) for JAVA_HOME (goto Control Panel->System->Environment Variable) in double quotes. Removing the quotes fixes the issue.

On Ubuntu 13.10 x86_64, updating (to v. 0.3.1 at the time of this writing) also fixed the problem.
To update, as some already listed, just click on "Help -> Check for Update".

NOTE: If you have both Oracle (Sun) JDK and OpenJDK installed
please validate either STUDIO_JDK, JDK_HOME, or JAVA_HOME environment variable points to valid Oracle (Sun) JDK installation.
See http://www.jetbrains.com/help/phpstorm/installation-guide.html?section=Windows#h2linux for more info on switching default JDK.
I think this is the problem. You must switch android-studio's jdk to the right path.
