Latest setuptools setuptools==71.0.1 broke pytest

[otrejo-soria]

Not sure if this will be right place to file it, but since it seems to happen with pytest, I am filing it here.

Current pytest version

pytest               8.2.1

IF I install

pip install setuptools==71.0.0

I can run pytest successfully.

This is a issue with setuptools, it's seemingly vendoring a package that's not vendoring safe

Its not clear if we can work around that

It seems there's already a bug fix release to setuptools from 3 hours ago, please check the latest patch release

[jaraco]

Was reported in pypa/setuptools#4480 and fixed in v71.0.2. Closing, but do please report if for whatever reason it's not fixed for you.
