I deleted a world that was about 300 mb in size and it didn't change anything.
I deleted the game again last night and reinstalled it after the update came out today, too.
Hey Mojang, today's update didn't fix anything. It still takes more than five minutes to load the game and it crashes right after I enter my world's.
I heard and did the exact same thing you're talking about, Ricardo. It didn't work for me either.
I have the exact same problem. My Minecraft on the Switch is at 13.1 but it started much earlier than that. I've been dealing with the occasional crash or two for about a year but it has gotten progressively worse to the point that it has become unplayable. It takes several minutes for the game to start up too. Single player mode crashes before I can even take a single step. Up until a few days ago, multiplayer and realms didn't really crash. That is no longer the case. I can only play in these modes for a couple minutes before the game crashes now, and that's if I'm lucky. I tried uninstalling and reinstalling during both 13.0 and 13.1 and it has made no difference.
I have the same issue as Paul Ellis on my digital copy of Minecraft for Nintendo Switch.
