android studio put itself into read only mode for all files

Steps to Reproduce

standard development for flutter, somehow android studio decided every file was read only (which was not the case). seems clearing .idea directories fixed the issue. but this sort of behavior isn’t acceptable.

begging that flutter move away from android studio as the defacto development environment. its extremely fragile and brittle. to the point where everytime I’ve tried to use android studio I spend more time debugging the IDE than actually writing code.

1. Close Android Studio.
2. Save .idea folder for future restore (if something happend)
3. Remove .idea folder
4. Start Android Studio and open project.

This issue is STILL happening. I would really appreciate a fix. I am spending more time uninstalling and reinstalling IDE’s than developing. And no, the lock icon to writeable does note work.
