Hmm, well for one thing I'm on a Ryzen 7 3700x 8-core, 32gb of RAM, and an AMD RX 6600XT, so I do wonder if the differing setups has anything to do with it.

But yes, you grabbed the correct one, that wasn't a hash, just part of the release name of the nightly build.

My only guess from here would be to try to check logs and/or use something different than Steam.

For example, I couldn't even get the setup.exe running in Heroic, but it launched with no problems in Lutris. My go-to when things aren't working is Lutris, and then launch every pirated game through Heroic Game Launcher, personally. I manually add it to Heroic after Lutris does all the work.
