MuseScore 4.4 file is corrupted

Hi
So as I plugged in my headphones (I had my score open), PC crashed and when it rebooted and I tried to open my score, I got the following error message: "File "filename.mscz" is corrupted. This file contains errors that could cause MuseScore to malfunction." When I clicked Open anyways, I got an empty canvas. I tried to unzip the .mscz file, but it seems that the .mscz is empty and does not contain .mscx file. I also tried to open the backup, but it displayed the same error message. I have attached the original file.
Please help me restore my file.
Thanks
