We warmly welcome you to the Friendly King Community's Candy Crush Saga forum.😉
We're sorry for your problem. In fact, if you change your Facebook or Kingdom password without logging out the game, the game app will be corrupted. Moreover, such problems are likely to occur for various reasons. If you find the image below while connecting game to the server, you can be sure that your game app has been corrupted.
In that case, you must uninstall and reinstall the game app.There is no other way. You will lose all the stored boosters to do this, but will regain your gold bars and game progress.
Let me know.
