Score Corrupted - Please Help

Hello everyone, I hope that this cry for help finds you well -

My score has been corrupted at the ending, rests are in places they shouldn't be - and while I tried to fix this on my own my fear is that I might or might have made it worse.

If the corrupted measures can just be turned into whole rests I can do the rest from there.

My OS is Windows and I tried using OneDrive for an earlier version of the score but could not find anything.

I was using Musescore 4.

Thank you so much.
