After successful use of newly-installed MuseScore, subsequent attempt fail at "Loading scores..."
After a clean install, everything works great for loading an existing .mscz file and saving it. After quitting MuseScore (MS), and during a restart of MS, the banner screen hangs on "Loading scores ..."
During attempt to uninstall MS, am advised that Qtwebengineprocess cannot be removed as it is being used. I delete that process using Ctrl-Alt-Del, and continue the app removal which appears to complete successfully (using Revo Uninstaller which also removes many registry entries).
I then reinstall MS, which then I can use successfully as long as I do not quit. After quitting MS, and when I attempt to start MS again, the banner screen hangs as I earlier reported, beginning the removal/reinstall cycle all over again.
The workaround is repeatedly removing and re-installing MS which is tiresome and time wasting. I doubt it is the .mscz score as it loads successfully after a clean install.
