‘‘A player is in another dungeon’’

Hey @ozgurboyraci

Hope you are doing great and apologize about this inconvenience.
I would suggest to close the game and run a steam files verification. You can find the instructions here: Steam Support :: Verify Integrity of Game Files

Let me know if this helps!
