My son's "Mineworld" save file was corrupted last week on our Xbox One X.  Our external backup drive was also bricked as a result.  We followed all of the usual fixes: a hard reset of the system, uninstall and reinstall and opening Minecraft on our new Xbox Series X.  The file will not load and comes up as corrupted through all means.  

     After starting a new file on the Xbox One X, my son is running into a corrupted save file again.  The new file is loading with him stuck in bed without being able to leave.

     My son absolutely loves Minecraft and has sunk a year into his "Mineworld" world.  It's been very upsetting for him to lose multiple save files.  Please advise.
