itch.io

i'm getting this error 

This application cannot be opened - when I open it from finder and:

The application cannot be opened for an unexpected reason, error=Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x600000c24030 {Error Domain=NSPOSIXErrorDomain Code=111 "Unknown error: 111" UserInfo={NSLocalizedDescription=Launchd job spawn failed}}}  - When I try to open it up via the terminal 

Same problem, I've extracted the mac version from the rar but the application just won't open at all
