Unable to Sync World

I have tried multiple different methods to get into my minecraft world but it won’t sync the world fully it either won’t sync at all and says unable to sync or it will do about 40% then show a message saying can’t sync fully because of world either being corrupted or migrate to another device whilst I am on a new xbox series x. The last time I played this world was 7/16/25 and it worked then I don’t understand why it won’t allow me to sync the world now. The world does have a large file size so I made backups in case of this issue and the backups don’t work either. I heard the two possible issues are the one with the sync and the sync because of the microsoft storage limit but the world is way below that. I was wondering if there was a way to fix this issue. I have used purchased addons from the marketplace on this world too and was wondering if that caused this so I was intending on re-syncing removing the addons and making a clean version of the world to play on. How can I fix this?
