Minecraft won't stop crashing on load. Why?

I've tried most things, and nothing will resolve my issue. Basically, as soon as I open Minecraft Bedrock, the thing crashes while it's loading up. I've restarted, offloaded and reinstalled. I am NOT deleting and installing, as then I will lose my worlds. I can't really send a screenshot of crashing, as it's more of a in-motion issue. Please help me, I also force closed all of my apps, reopened Minecraft and it still didn't work..
I would like a resolution.

Yours,
Ali
