You could try deleting /var/guix/profiles/per-user/$USER and running
"$THE_GUIX_OF_ROOT pull" and "$guix install ...". I don't see why that
wouldn't work, but I've never tried it and 0 warranty.

Could you search for "show-derivation" in the back-up? E.g. with grep -
rF show-derivation. Maybe there's a leftover from when you used nix
somewhere ...
