You didn't specify which version you were trying to install, but PyYAML 6.0.1 fully supports Python 3.12; older versions will not. See #736 if you insist on trying, but IIRC there were other 3.12 compatibility fixes required in 6.x). You'd probably be better off just getting whichever project is depending on an unsupported version of PyYAML to upgrade.

Closing as duplicate of (many issues related to Cython 3 pins).
