i bought minecraft dungeons 3 days ago and yesterday when i wanted to play ther was a white pop up when i pressed a button at the campfire loading screen

as there is nothing on that white pop up screen i just hit exit and then there is press a button to continue again and then it just keeps rotating i let it rotate for almost 10 hours and nothing changed 

i alredy reinstalled it twice and now with deleting my heros and i do like the game so thats pretty sad so is there anyway to fix it cause i found viedos for the switch and ps4 but nothing for windows 

picture 1 is the pop up and the second picture is after 10 hours
