Android studio : kotlin-idea.jar contains invalid plugin descriptor

 

I tried to update the Android Studio Kotlin plugin and it fails :

File '~\AppData\Roaming\Google\AndroidStudio2021.2\plugins\Kotlin\lib\kotlin-idea.jar' contains invalid plugin descriptor

Then, I tried to downgrade, disable... without success.

So, now, I'm making a new install of Android Studio...
