When I open a minecraft PREVIEW world it's kicks me out and brings me back to the menu......

When I try to start my world it loads for a minute or two, black screens, and then quits minecraft and brings me back to the xbox home menu. I've tried dozens of times and have just now tried this and still nothing.

I resetted up to four times in which I couldn't even get to the setting up menu unless I left it unplugged for more than an hr and it finally stopped giving me an error message and allowed me to setup afterwards this is my first encounter with my minecraft
world not syncing and it's been doing that the other saves I have do sync but when they do it's just been kicking me out of the game and back to the main menu all I want is to get back my main world which says I last played on the 27th of septemeber this year

My Minecraft world kicks me out for a couple reasons like world corruption and not enough space for data, is there a fix?

It is kicking me out of the game after like 3-5 minutes it keep on deleting stuff that I built or did a minute ago so that was is happen and I don't like it.

It is on my phone not Xbox it keep on kicking me out

After a while of messing around I found a solution that works well enough. Ill write it here in case someone else has this problem in the future.

- hover over Minecraft and click start button (make sure you have closed Minecraft)

- open "Manage game and add-ons"

- click "save data"

- then "delete all"

- open Minecraft

- create a new world

- quit back to menu and your worlds should be working

(Note: the original world I was on when the Xbox unplugged is unplayable and if I click on it, it will continue the glitch and will not let me open any more worlds. I thinks it corrupted or something like that.)
