I'm not sure if that's related to homectl - it seems that you're trying to specify User= and Group= within a user service. The whole "systemd --user" service manager (user@xxx.service) is unprivileged and runs as your user, so it cannot change its UID anyway or set any supplementary groups except those that it already has.
