Mac Catlina error in opening

I downloaded Stepmania for the first time (5.3) but my Mac didn’t want to open it as it didn’t recognize it. So I opened it through my settings as suggested, however it still won’t open. The new error message now states, “Stepmania quit expectantly”. Is this a bug or something more I need to do?

Did you change your macOS security settings to allow StepMania before running it? You can find the instructions on how to do that here:

Also, please make sure you’re not trying to run the ARM/Apple Silicon M1 build on an Intel Mac (or vice versa), otherwise it won’t work even after doing the steps above.
