MCD / MCD-7259

i was downloading Minecraft dungeons cause i already had it on Xbox but i wanted it on computer to so when it downloaded i opened it up and it was the normal loading screen and it said press any button to continue like normal then it made me sign it i thought that was weird but i still signed in then when i signed in it had a white box with a x in it when i pressed the x it sent me back to press anything to continue then i pressed something then i was going  to menu for three seconds then it took me back to the press anything to continue screen and said i signed out of my account when i never even got to the menu yet then whenever i press it again it just does the same thing from the start.
