Since this started Appearing I cant play Minecraft Dungeons. I even Updated the Game and reinstalled and deleted all of my saves... and still this Glitch remains.

after I close this window it asks me to press any key again and then it starts loading forever and never finished.

Nothing Works. I have tried everything.

I know this glitch and similars were reported before. I just wasnt able to find my version of it with the white text box on this version of the game.

EDIT:

I have deleted my saves for nothing!
