Corrupted File

Hello all,

As of this morning, I updated Musescore to 4.3.1. A score I was working on last night (and saved since then) has since become corrupted and is listed as empty. This cannot be the case because the thumbnail of the score is still there and has music listed on it. The file size is also 538mb which obviously cannot be the size of an empty file.

Has anyone else experienced this? I don't see how this file can be empty since I had just saved it the night before. It does not open in Musescore 3 or Musescore 4. I tried reverting the updated, yielding the same results.
