Qubes-builderv2 help needed

I’m currently trying to build a template using qubes-builderv2 and I havent figured out how to get a working yml to build a template.

I followed the README.md from qubes-builderv2 all the way up to part where you run ./qb but I can’t seem to get any setup working, the examples in the qubes-builderv2 repo are all nonfunctional in my experience, and when I use configs from QubesOS/qubes-release-configs subdirectory R4.2/ it always fails at ./qb package fetch and ./qb template <fetch, prep, etc.> does nothing.

My end goal is to build the Gentoo template with a stage3 tarball using a custom profile because I want to run musl + systemd with the OpenEmbedded patches (like the work present in the 12101111 overlay)

Apologies if this post is a word salad, I’m currently writing this as I’m preparing to go to sleep after spending the last 3 days (I slept between each day of course) trying to figure this out, thanks in advance! I’ll probably proofread this again in the morning
