Yeah, web version seems to have issues on some devices. Unfortunately, Mac version is not signed, so it is not that simple to start it. I believe that on Mac it needs to be removed from quarantine, I haven’t been doing that before and I don’t have a Mac on hand :( Thank you for your comment. I hope you manage to run it.
By the way, which version of MacOS are you running? I can confirm some people can run it on MacOS BigSur with Intel processor.
