I tried the following commands after switching back the package profile to
previous state.

$ which guix
/root/.config/guix/current/bin/guix

$ echo $GUILE_LOAD_PATH
/root/.guix-profile/share/guile/site/2.2

$ echo $GUILE_LOAD_COMPILED_PATH
/root/.guix-profile/lib/guile/2.2/site-ccache:/root/.guix-profile/share/guile/site/2.2

But I can't reproduce the bug now since I cleaned up all profiles in pull.
