My worlds have become corrupted.

I have been working on a world for 4 years consistently now and it has been corrupted since restarting my xbox to fix a saving error. The world worked just fine until about a month ago so I waited for a bug fix. The new 1.19.60 performance update did not solve the issue. I have looked at the original xbox they were made on, and they were corrupted there too. Is there any chance these worlds can be recovered? Is there anyway I can give you the file to uncorrupt it?
