Your Mac build may need re-uploading; the .zip file is 178 bytes, and is completely empty when unzipped.
Also, if you're creating that Mac build from a Windows machine, the execute permission on the executable won't be correctly preserved, so unfortunately anyone who downloads it will have to run `chmod +x` on it if they are on the latest version of macOS or the app won't run no matter what. No great way to fix that without your own Mac to run the command and re-zip it from :(
