Maybe this needs to be raised to actions/setup-python ? 3.11 is specifically installed differently. And it looks like something is going wrong during install.

See actions/setup-python#536 (comment) :

Since 3.11 python is installed from the official Python macos packages and hostedtoolcache files are nothing but a links to the default paths for sake of backward compatibility.
