I think you can download the version from the Shop, that is still the previous version
Somehow Mac now removes the executable bits from the application. You need to chmod them manually in the terminal... I'll see to find a workaround.chmod +x Visionaire\ Player.app/Contents/MacOS/Visionaire\ Player
It was already not working. I got reports about that. It's the catalina update.
Needs to be done on a mac and can then be rezipped. Or you wait some days til I've figured it out.
