This issue has been fixed in Edk2 trunk 20b292d0cdf7dce58d824fdf9ab1613c2a1ad2ec.

Edk2 Build supports Python 3.8 & Python3.9 both.

Thanks

It looks like a Python 3.8.x vs 3.9.x issue.

Do we have a scheme to require a min Python version?

It looks as if you’re using Mu Q35 as your platform. Can you tell me what branch you’re on?
