Same here. I've done the StarfieldCustom.ini as well. Followed all instructions, but none of the mods work. Skyrim and FO4 were a breeze, can't understand why the mods are not working this time. FIXED Instead of creating a .txt I copied the StarfieldPrefs (and copied the Archive into it). Then renamed it to StarfieldCustom. Enable extensions. When I did I noticed it was ini.ini. The Prefs one automatically adds the .ini for you. I deleted the extra .ini and the mods are now working for me. Good luck to anybody still having issues. Hope this works for others.
