Jump-In-Event is stuck

(I play on PC, on Windows 10)

I am unable to play the event again. When trying to play again, it only shows "home" after going to jump in..
I cannot start a new game, I cannot resign.

Jump-In is my favourite format and I spend all my gold on it.

Please help me, so I can continue playing it.

(Before I reported the bug, I went on "Repair Game files". But it did not help. The game is still stuck. I cannot play Jump-In.)
