Installing from git repo breaks when upgrading pip from version 21.2.4 to 21.3

Environment

• Pythonnet version: 3.0.0.dev1
• Python version: 3.9.7
• Operating System: Windows
• .NET Runtime: All

Details

This fails:

1. python -m pip install pip==21.3
2. pip install git+https://github.com/pythonnet/pythonnet

with error message:

Error reading git repository information: Unsupported repository version 1. Only versions up to 0 are supported.

I first filed the issue under the pip project, but there it got closed with a comment about it being a Python.NET build system issue.

As a possible workaround you can set the environment variable EnableSourceControlManagerQueries to false:
