So I checked, and I did correct the problem, so I made a record

The problem is

The root of the problem is that some plug-ins don’t support higher versions, and then they can’t start. To be honest, it’s not humanized to start them directly

The solution is: go to this directory

C:\Users\{user}\AppData\Roaming\Google\AndroidStudio4.1\plugins

Then copy all the folders or jar packages (actually the plug-ins you downloaded), and delete the ones in the original location. Try to open them. If you can, use the binary search method to find out which plug-in is not supported, and then do not use this plug-in

PS: Note: you must copy before deleting, not cutting. You can understand everything you know PS

If it’s not enough to remove all the above directories, it may be that there is a problem with the plug-in (the probability is very small). The directory here is also a binary search to test

C:\Program Files\Android\Android Studio\plugins

Problems can generally be solved
