Minecraft app crashes after one second rendering game completely unplayable

Whenever I try to open Minecraft, it shows the "Mojang" intro for a short moment and then immediately closes. The game is completely unaccessible. No clue what the issue is but it is very annoying. I have not tried clearing cache, which may fix the issue, but I don't want to lose my worlds. This repeats infinitely as far as I can tell.
