Crashing after some gameplay

I’ve gotten very annoyed by crashing because even when there’s hot fixes or updates that state crash fixes I still have crashes. I’ve even had times when it has said the crashes have been fixed and I get on a world of mine and I crash 5 seconds after loading in. I’ve had crashes that happen minutes after loading and longer but the crashes never go away. I’ve had this problem for a while now and I’ve reported it a lot by now. I know everyone working on Minecraft is very busy but I do hope the crashing could be fixed permanently. I have no idea what causes it and I’ve done many things to fix it, even deleting the app and re-downloading it with the price of losing all of my data on the app.
