I’ve tried all the links and it says cannot open ‘OutsideVoice’ because no application can open it , it also says that it can’t be opened , I don’t know if it’s just my Mac, or something else

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?
