The Arch wiki may have some ideas for you - tl;dr is that GDM uses a global dconf db over in /etc/ and this might be the root of your problem (these configs might not get cleaned up with a --purge?) I’m a LightDM user so best I can do to help: https://wiki.archlinux.org/title/GDM#dconf_configuration
I appreciate the help, I did use dconf editor but I haven’t manually cleared these out and updated dconf I’ll try this out, worst case GDM is still busted.

Update, I have made GDM unusable (not just broken styling), progress!
Wonderful update
