Same for me, I renamed the project root folder and then it broke. Even if I deleted the .idea folder it does not work again.

Edit: Got it to work by closing all open folders that were opened via "attach" until I was at a blank screen again, then go into all these folders, delete the .idea folder, then reopen them all (requires configuring your interpreter again etc.)
