I had the same issue, and I kinda just figured out how to fix it, Its the same solution as when somebody get the white screen while its open. Go into the installation location of your copy of minecraft dungeons, and from there you go "/dungeons/dungeons/Dungeons/Binaries/Win64" then start Dungeons-Win64.exe
