Musescore 3.4.1 won't open on macOS 10.15.3

• Feb 5, 2020 - 22:24

My MacBook Pro 16" updated to 10.15.3 last night and now MuseScore won't open anything at all and if I right click the icon it just says "not responding"
I have tried
-re-downloading musescore
-Right clicking the icon and opening it from there.
-Opening through downloads in finder.

None has worked. It gave me the "Malicious content" warning and I allowed it as normal, yet it still doesn't open anything.

Help!!
