Retreaving corrupted files

I had an update to my Windows 10. later that day, I went to work on my game and I could not find the level/map I was working on in the browser. I have been trying to uninstall updates to save all my work but have not had any luck. worse from that I have realized that actor files have been lost too. I have put so much time into these resources and hate that I have lost it all! Is there anything I can do to salvage my work? How can I retrieve/fix corrupted files?

Note: I can still find the .umap and the .uasset’s in windows browser but if i try to import them back in the project crashes. I have also tried new projects to no avail.

I was able to recover it via auto saves!
