Musescore 4.4.4 suddenly stopped opening

A few days ago I went to open a large orchestral score I was working on and it will no longer open. This has happened once before a few years ago. It is very frustrating and kills the creative workflow. My project has come to a screeching halt. I airdropped the file from my iMac to my MacBook Pro and it opened but the screen is so small. When I try to open the file on my iMac I get the splash screen that says loading.... then it closes. I have left 2 messages with MuseScore but other than what appears to be an AI generated response telling me to contact another person at MuseScore I have made no progress. Tonight I tried to delete MuseScore and MuseHub but that didn't do it. I need to get it back up and running on my iMac. What is the solution?

Thanks
