Score saving issue (program freeze)

I just installed Musescore 3.0.5 after having version 2 for quite a while. After installation, I was going to transfer a score I transcribed and it moved successfully, but when it moved over and I hit the command to save the thing the entire program froze and my mouse cursor turned into the loading pinwheel. I couldn't do anything else other than force quit the program. I will leave the file of the score I was working on down below, however this is a program problem rather than a score problem, as I have loaded others. At this point if I try to load the score the program just closes altogether and it's leaving me extremely aggravated. I click the score, click restore session, then the whole thing just closes. Please help me resolve this issue.
