Musescore will not load or display scores.

Unable to open scores with Musescore 4.44. Click on App, starts up with "loading" message, message disappears, Musescore icon appears on task bar. Click on task bar icon and blank screen (possibly Musescore desktop) with score title in upper left appears but score does not open. Have tried Repair, Uninstall and Reinstall with no improvement. Example of score that will not open attached. Am unable to work with scores in progress or already completed scores.
