What happens when you try? And what have you tried?

Ok- I'm assuming you're on Catalina. What happens if you right click OutsideVoice and select Show Package Contents->Contents->MacOS, right click Use Your Outside Voice (the only file in this directory) and try Open or Open with Terminal? If that doesn't work, can you right click/get info on it to see what "kind" of file it is being registered as?
