I've been playing on this world since April of 2019 when the village and pillage update was released. I've had no issues running the world. Back in the day, it was running on my Xbox One original. I decided to load up the world yesterday after Caves and Cliff's part 2 was released, there was no issues at all. Although yesterday, my new Xbox Series X arrived. I tried loading up the original world on my Xbox Series X, unfortunately I got an error saying "data failed to sync." Then it showed that the world was "not fully synced or that the world was corrupted". I am very sure it was not corrupted as this is the first time I've only hearing about this. I did make 2 backups of my world though before the update was released. The two backups work with any issues just the original save does not work. Any response would be greatly appreciated. 

The name of the world is "Village and Pillage Update"

The devices that were used are:

Xbox One Original and Xbox Series X.
