Pip fails to install PyQt5 (any version) in macOS Monterey

Question

I'm attempting to install PyQt5 through Pip/Pip3 in macOS Monterey. I've updated all Homebrew applications as well as all Pip installations using the recommended process. Every time I attempt to install the PyQt5 module, I recieve numerous errors. I've tried following some guides, and I've tried following related answers on this site. I've tried installing every version of this software from 5.12.0 to CURRENT. Here's the traceback:
