Describe the bug
I'm running through the installation instructions for Matter support, and ran into an error I don't understand. You can see the lengthy transcript here. Excerpt:

I have the same problem. After downgrading Python version from 3.12 to 3.9 it works.

I also had to downgrade python 3.12 to 3.9.2 to get past issues installing esp-matter on an M1 Mac.
