This is taken from our CI builds.

I can confirm this. We have the same issue.

A simple way to reproduce:

python3 -m venv env
./env/bin/pip install "setuptools == 50.0.0"
./env/bin/python -c "import distutils"

I am in the process of blacklisting 50.0.0 in our dependencies using setuptools != 50.0.0 in our dependencies.

I suspect this issue is the same as #2352. The error message is the same, so assuming so unless I hear otherwise.
