Python 3.11 is apparently not liking the 5.x builds of PyYAML for some reason, as far as I can tell. (More specifically one of its dependencies isn't handled well, but it's an upstream issue so no need to go into it here.) I changed the requirements and built with 6.x, seemed to have no impact on functionality and works fine with 3.11 (and should work with any Python ver >2.7, according to the developer).
