World disappeared from xbox

Obviously have countless hours into the game and after just getting mending from a villager, the game freezes and after it booted back up the world was gone. I tried resyncing with no luck. I’m really at a loss and this was the reason I stopped playing years ago on the pc. But I hope you can help, I’ve heard something about a cloud but the world is gone completely from my hard drive. Just a copy that was made on accident I turned to creative. Anyways, I hope to hear back
