My Xbox one creative world and and it’s back up got corrupted with the new update!

After updating to version 1.19.31 (which itself had various issues with installing) I attempted to load up my creative world, only to see a data sync failure. I tried again and my game crashed. After restarting the game, I found that my world had been corrupted. I tried with the emergency back up of the world to the same result. This is a large world and it agonizes me to see it possibly gone forever, after the days of work put into it. I don’t even want to open another’s world out of the chance I could also lose it.
