Subject: [PATCH] Fix Python 3.12 compatibility (#6965)

.joinpath with an empty argument no longer works as before thanks to this change in CPython: https://github.com/python/cpython/commit/cea910ebf14d1bd9d8bc0c8a5046e69ae8f5be17#diff-2e741d925220d74a9cc04cda1314d3649d9d189c0efc7db18e5387a51225b61c

This change mimics the old internal behavior by using _paths attribute directly.
