My world in Minecraft just stopped opening out of nowhere and giving an error when...

Not sure why I get the Error try 8 days running still not working, Tried at different time (out of ours gives error straight away basically saying come back later when we are open)

Stuck now got nowhere to go, just got a big white brick with a gears of war logo on it.

It just completely dissapeared out of nowhere. I was building in a personal world when it said disconnected from server and when I went to the main menu, I had to login to xbox again and then all my worlds were gone

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

Hi! I'm Rostom, an Independent Advisor. I will be glad to help you here. Sorry to hear about the issue.

Just to confirm, you have an issue synchronizing your data from the cloud?

If so, our best option here is to reinstall your game since you tried all the basics. The reinstallation process varies on how you acquired your game.

Hello, im ayden I forgot my email account for the original account but whatever. Almosts all of the worlds are openable and convertable there’s only one other world having the same issue. I’ve searched and haven’t found an answer. The error states nothing about the world being corrupted it just says it’s having errors converting the world. The minecraft xbox one version cannot open the world, and the newest version of minecraft cannot convert the world. It syncs xbox data and then stays at 0% before prompting the error “something went wrong with world conversion.” This isn’t all the sudden I’ve tried a few months prior and it said the same thing. Thanks for replying btw.
