So I checked it, and the problem was indeed corrected, so I recorded it

problem lies in

The root of the problem is actually that some plug-ins do not support high versions, and then they can't be started. To be honest, they can't be started directly, which is not human at all.

The solution is: go to this directory

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

Then copy all the folders or jar packages (in fact, the plug-ins you downloaded yourself), and delete the original location, try to open it, if you can, use the binary search method to find which plug-in does not support, Then it's ok without this plugin

ps: Note: Be sure to copy and delete, not cut, understand everything

If you can't remove all of the above directories, there may be a problem with the built-in plug-in (the probability is small), the directory is here, and it is also a binary search and test by yourself

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

The problem can generally be solved
