Build.py fails at build bindgen

[Hark64]

I tried to run "python3 build.py --tarball" but it fails at build bindgen with some sort of syntax error.

I'm on Windows version 23H2 (22631.4317). I was in admin mode in command prompt. Not sure what is going wrong here. I can't find this error described anywhere else online.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 62859b2c chore: Release
