Game crashes whenever I try to load up any world.

So recently I've had a HUGE issue. Whenever I try to play Minecraft on my Nintendo Switch, it loads up fine. But the second I join any world I have created, the game crashes during the generation. I'm not sure if it's corruption because I checked and it said it wasn't and I also have deleted my save data a bunch just to play. The crazy part is that even when I make a new world, the world will generate fine, but whenever I try to load it up again, the game crashes. It's very frustrating and I have been debating deleting the game all together. Also, I can't stay signed into my Microsoft account which is very annoying but unrelated. Any help would be great and appreciated!
