We warmly welcome you to the Friendly King Community's Candy Crush Friends Saga forum.π€
I see your game app has been corrupted. Without logging out of the game, there may be a problem if you change your Facebook or Kingdom password.Β
In that case, you must uninstall and reinstall the game app.There is no other way.πΒ You will lose all the stored boosters to do this, but will regain your gold bars and game progress.
If you haven't saved your game with an account yet, let me know.
