I have been using Android studio for quite a while now, but one day the application just suddenly go wrong. When I try to click on my directories to find the files to import or open, the application gets incredibly slow and not responsive at all. When I finally successfully switch to the intended directory where my file is stored, the directory doesn't show anything that can be opened (as shown in the screenshot, where I try to open a file from my download folder but it doesn't show anything).
This error message kept showing up as well (open file operation failed: The open file operation failed to connect to the open and save panel service.)
I have tried to uninstall and re-download Android studio for several times but the problem still remains.
