So, for anyone out there having similar troubles, there were some leftover files referenced under /home/poppy/.config/systemd that I was no longer using (and that should not have existed anymore), but the system still had entries for them. This caused the quadlet generator to fail when trying to convert the rest of the quadlet units, and as a result nothing was working. After deleting those files and reloading the systemd daemon, all the containers started working again.
