Error Updating to MDL 1.3.1 in 3.3
OS: macOS 10.15, Arch.: x86_64, MuseScore version (64-bit): 126.96.36.19990, revision: 4761df6
Updated to 3.3 and tried to update to MDL 1.3.1

Error: Cannot Import extension on read-only storage: Macintosh HD
I'm the admin account on this machine.
As a side-note; MDL sounds don't work now. I'm unsure how they're related, but I cannot use MuseScore until this is resolved.
I tried removing the MDL folder. This changed the "update" button to "Install", but the same error occurs. I've restarted the computer and MuseScore several times.
