Hmm did you try what's explained in the macOS related devlog? What happens when you do? Please don't hesitate to contact me on Discord so I can try top help you. ;)
Ya I tried that command and pasting the application, same thing. Saying it's corrupted and I should eject. Even turned off Gate Keeper to see if that would help. No luck. Hopefully you get a working Mac version soon. Let me know if you do.
