[SOLVED] Python's setuptools is failing to install at random in my Github Actions workflow

For the past few weeks I've noticed my Github Actions workflows failing randomly when installing the setuptools library. Usually running the workflow once or twice will clear the issue, but I am unsure on how to avoid it happening in the first place.

Github Actions runs on: ubuntu-latest
Python version: 3.10.13 (tested with 3.11.6 and 3.11.8)
setuptools version: set to 69.1.1 in my pyproject.toml, but poetry decides to update it to 69.2.0

The installation is made through Poetry without a virtualenv (poetry config virtualenvs.create false && poetry install --no-root).

Error log:

...
- Updating setuptools (65.5.0 -> 69.1.1)

  ChefInstallError

I've tried changing the python version in case it is a bug with a specific version of Python, and I've also tried installing setuptools before Poetry with pip in case it is a poetry bug, but it made no difference.

It has been working perfectly well for months, and now 1 in every 3 runs will fail with this error. Any ideas?
