Lost My Worlds/How Do I Recover My Worlds (Windows 10)

There was an option where I helped you recover lost worlds

Have you used that option?
If it is the case that yes, and you still do not recover the lost world, I believe that it is no longer possible to recover it
A greeting!

If you still can't recover your lost worlds, they are probably gone, so make sure you back up your worlds before uninstalling the game next time. To do so, follow the process described in the link above to access the folder containing all of your worlds
and just copy your saved games anywhere. To restore them, simply paste them in the correct folder and check if they appear in your game. If not, try to follow the procedure from the link to restore your worlds.

I hope this helps you!

Sure thing! Hope you can recover the online progress
