I have been creating my world for about a year. Sometimes it would crash but nothing that a simple closing the app and reopening wouldn’t fix. The World is about 54MB. I use an iPad with iPadOS 15. About a week ago, right after updating to the Minecraft PE version 1.17.32, every time I open my world, i can use it for about 30 seconds before it crashes the app. I've tried erasing and downloading the app again and it still crashes. But it is only with that world, because any other new or old world works fine. I updated to version 1.17.34 as soon as it came out but the update didn’t fix this bug. I really hope it gets fixed soon because it has taken me a lot of time to make that world.
