MCD / MCD-6939

Since the new update, once I try to play the game, there's a blank white window appearing and a voice over saying "Press the left mouse button to close". Once closing the window, I press the screen to play yet I am stuck in the loading screen. I can't play the game unless I run it from: C:\Users\UserName\AppData\Local\Mojang\products\dungeons\dungeons\Dungeons\Binaries\Win64\Dungeons-Win64-Shipping.exe but I need to relogin from there
