UPDATE 1 (MAIN)

While I was playing my minecraft bedrock edition world, I randomly crashed with no explanation for it, I never injected a out dated client, install a virus or random broken addon, the only things I ever use is small texture packs that make the game easier to understand and re-texture things like glass. there is a small detail that I've noticed while this happened the 2nd time on a different world, this occurs a few seconds after joining your own world I can't confirm this information sense this only happened two times, but if I actually wanted to I'd probably have to test it 5-7 times

UPDATE 2:

I opened my alt account on to the same world (Example of what I mean by "alt" your main: Player to alt: Player(2) your welcome) to test out an execute command but when I got both main and alt on, minecraft flat out crashed, another thing is while you load back into minecraft after crashing your screen might appear black instead of red. I don't know if this bug effects the sentence above (Update1) but what I know is this seriously needs to be fixed.
