`tox` fails all setup on MacOS (`subprocess-exited-with-error`)

[martimors]

Describe your environment
I'm following this guide. I've contributed a feature and would like to run two unit tests. Seems to me the way to go is to run every single test, on multiple python versions, but I find this excessive when my feature scope is so small (after all isn't this what CI is for).

I'm using a venv with python 3.11.5 for tox.

Steps to reproduce

# On MacOS with python3 version 
tox

What is the expected behavior?
Tests running

What is the actual behavior?
Perpetual error loop (repeating for each and every package)

Additional context
I just want to run two unit tests, I should not have to run every single test locally in a tool that my IDE doesn't support (tox).
