Ususally the Mojang logo comes up for about 3 seconds, disappears then there is a blank screen for 1-2 seconds and the main menu comes up.
Now, the mojang logo flashes on screen and the app goes blank for about 10 seconds. Then the app crashes and I can't play.
To trigger this, (I think this is what did it) I tried to install a world from the internet. (https://hypixel.net/threads/zombie-apocalypse-minecraft-adventure-map.662/) and the app tried to import it, got to the end and crashed.
Thank you for your report!
Crashes such as these are now logged automatically, so will be investigated further by the development team internally.
