Corrupt Score, I cannot open the file without MuseScore crashing

Hi all,

After some work on this arrangement, I finally finished it! Just in time for it to corrupt before I could save the parts as PDFs! MuseScore crashes instantly when I try opening the file. I've tried it on other computers, renaming it, moving it, making copies, unziping it, compressing it, and so far no luck. I'm very frustrated so any help is greatly appreciated!
