Thanks, anton. And apologies – I overlooked that Troubleshooting section.
Unfortunately I'm still not able to get massCode to open.

Option 1 (System Settings) isn't available – the app doesn't get shown in the Privacy & Security settings.
Option 2 does stop the 'damaged' error message from showing, but the app instead now opens and immediately closes.
