Musescore suddenly wont open - black square instead

• Nov 8, 2020 - 23:01

I've been using the latest version of musescore for months with no issue then suddenly the other day when I opened up the app it starts to load as far as the "creating main window" text before a large black square appears covering up the blue musescore loading window. It then freezes. I can't even quit the app, I have to force quit it every time.

I'm using a MacBookPro running 10.14.3. I've not updated any software lately so don't understand the sudden breakdown of musescore.

I tried reinstalling the latest update again (though not sure how to uninstall the previous version, it just overwrote the version I had on there).

Please help.
