I would seriously recommend using a file explorer for xbox and save your world files to a thumb drive before you open the updated game...
Same here. I think this is why there are so many missing world and sync issues going on. Luckily I saved those files before doing the clear local saves they recommended and resetting console and reinstall. I was going to paste the worlds back but the folder has just disappeared. I was able to transfer back to xbox from pc using realms and backup download option.
As long as you haven't cleared local saves or reset the console the files should still be there in the folder to copy and save. You have to get a adv files full control to find the files on the Xbox. Copy those world files at all costs if you want to save your worlds. And this is my fix since no one would help me I helped myself. I can walk you through it if needed.
This isn't a fix. It's a way to save your hard earned worlds like my 5 year old one. They were on the Xbox one s. I listed how I was able to salvage my worlds from xbox and move them to pc and phone and then once safe created a realm and put them back on Xbox. Still unable to sync on Xbox though. That's where the bugs live...
If you haven't reset or cleared local saves I found a way to get the worlds.
Do not reset console or clear local saves until you copy the files.
I added ADV Files (full trust) and copied all of my worlds from the folder. I used a tutorial to find the files on the xbox. I copied them to a thumb drive that I had formatted on my pc. I then pasted the worlds into the minecraftworlds folder on my pc and my phone.
The worlds work perfectly on both the pc and the phone. I then created a realm and uploaded the worlds to the realm and then back to the Xbox. Now I have backups everywhere.
There is still a world sync issue to cloud, so basically no cloud saves until they fix the bug.
They are no longer using the old folder to store the world files on the xbox or there is an issue with it saving because I wanted to paste the worlds back into the packages folder I had previously gotten them from but it was no longer there maybe that's where the bug comes from?
Whatever you do don't reset console or clear local saves until the worlds are copied anywhere but the xbox.
I have exactly the same problem. I lost absolutely everything on the xbox one. The game is stuck in an endless sync cycle. Even after following all troubleshooting steps.
I was however able to get advanced files for xbox and transfer the worlds from the packets/world saves folder and copy them to a thumbdrive and recover them on my phone and pc minecraft. Unfortunately the pc and phone versions run slow or not at all for me. It would be nice if I could just transfer them back to xbox but that is impossible I guess.
If possible at least you may be able to save the worlds for a time when xbox minecraft is fixed using the same method I did.
This world sync bug must be caused by the missing local state folder for minecraft after the 1.19.31 update for xbox. Which also causes world loss and corruption. The files for the updated game are missing. This is the issue everyone on Xbox is facing. Duplicate game tiles, sync issue, world loss.
