Hey there, I tried this on a macOS 10.15.3 and it would not open. The error message just says "The application “TheMessengerAssist_MacOSX” can’t be opened."

Thanks for replying! I tried to look into Security & Privacy pane, but there is no button there for me to press. Also the alert shown with the error message isn't the same error shown when an app is from an unidentified developer.
I dug into the mac logs and found this, hope it helps!

I appreciate the additional info! I've updated the mac build to hopefully resolve the issue. If you're willing to give it another shot, try downloading a fresh copy of the game. In researching this a bit, I've read that another potential issue is that the game may not work correctly if you use an app other than the default Archive Utility to unzip it.
