--------------------------------+------------------------------
 I'm really not exactly sure where this is coming from but an older version
 of setuptools gets installed which is itself not compatible with Python
 3.12

 Here's how to replicate it

 This produces the following error message

 I'm not sure whether the problem is being pinned to pip==22.3.1 or another
 dependency upon an older version of setuptools.
