same heree on a mac! its been saying "this application can't be opened" :'(
When you're about to open the game:
Right-click (or ctrl-click) and select "Open"
It might present the "This application can't be opened."
If it does, then repeat the above instruction and the second time should present an option to allow you to "Open" the app anyway. It wont ask you again after that.
If that doesn't work, then the devs will need to apply a fix 🤷 Hope this helps.
