the same exact thing was happeningg to me! i couldnt use the normal mac one but the alt had the static
I had the same issue where the normal mac version was static and the alt mac one said I needed permission. I changed the permissions and now it works!

chmod +x /Applications/Art\ School\ 2k19.app/Contents/MacOS/Art\ School\ 2k19
