@dmitry-shibanov could you take a look?

[ablatner]

I'm able to work around this with the expected pip command:

    - name: Install setuptools
      shell: cmd
      run: py -m pip install --upgrade pip setuptools wheel

Hello @ablatner. I've tried to reproduce the issue but it works as expected. Could you please provide a public repository to reproduce the issue?

[ablatner]

This seems to reproduce it: https://github.com/ablatner/windows-runner-test/pull/1

It calls setup-python with 3.9.13 and then runs a script that imports setuptools.extern.

Note that this uses windows-latest instead of windows-latest-8-core because it's not inside my organization.

[ablatner]

As in my org's private repo, this works after manually installing setuptools with pip: https://github.com/ablatner/windows-runner-test/pull/2

@dmitry-shibanov this is still an issue, demonstrated by my test PR.
