Problem playing minecraft dungeons? Where do i need to report this?

Behavior reproduceable on my xbox:

I was playing minecraft dungeons on my xbox one and when a second player turns in with the controller, the game is crashing.
Character loading and then crashes turns black and going back to login.

What did i do:

• I already sign

• Rebooted xbox
  signed off the other account and deleted the leftovers in the profile of minecraft dungeons.

See example clip.
