Minecraft sync data not loading. Corrupted

If it's saying the files are corrupted then not much can be done. Hail Mary attempt I can suggest is attaching an external storage device and copying the world file over to it. Plug it into a PC and google/youtube for help to continue on. Not an official
fix but as last resort suggestion and there is a way to go into the files and maybe find what is corrupted exactly. Sorry this happened.

I uninstalled Minecraft and I can now see the world on my world list but whenever I try to edit or load the world it says “Failed to sync world data the world is not fully synced or has been corrupted try playing the world on a console where it’s in a good state and try migrating it again”

There are many reasons for why this is happening, one reason that comes to mind is that there is corrupted save data: It's possible that the save data for your Minecraft game on your main profile has become corrupted, preventing the game from loading. Try deleting the saved data for Minecraft on your main profile and start the game again.

Hey Josef, I recently went over to a friends house, and when I signed in with my account, It loaded the worlds successfully! Then, when I went home, I opened Minecraft and sure enough, I re-downloaded the game and low and behold my worlds were back! I think this could be a very useful fix to any future world corruption/ data sync problems to any other fellow Minecrafter's!

I've tried several other games, and they seem to each need to sync my data back to them, but they have all worked so far. Only Minecraft has had anything corrupted. Sad. That was a good survival world.
