This has probably to do with the Mac safety restrictions. The app has to be "allowed" to run on your OS.
Please try the following:
1st.
3rd party App allows:
sudo spctl --master-enable
sudo spctl --master-disable - this one
sudo spctl --status
2nd.
Allow an exact App to run:
sudo chmod -R 755 App
"space after 755 + drag the app from Mac folder"
I hope this helps you. If the game still doesn't work on your end, feel free to jump into my Discord and I'll try to help there.
