I have the same issue. It has been open before, in issues #3892 and #4014.

The problems only exists on intellij plugins. The same project works on Visual Studio Code. FYI, the problem consistently happens on an older (slower) mac mini but never on a new, faster macbook pro, which supports the theory that it is a threading problem.

i fixed by uninstalling/deleting flutter folder, installing powershell 5.1 cause im using windows 7 SP1 ,then run flutter doctor. and its working now, the device became avaiable
its seems like the problem is , im using windows 7 which is only has powershell Version 2, but in order to upgrade dart, you need powershell 5.0 or 5.1, this is main problem, if dart failed to upgrade, it will became no devices or devices selection stuck at loading in your android studio. i hope its help you guys
