Right.  This is the same issue as
<https://issues.guix.gnu.org/issue/41384>.

TL;DR: Upgrade (or downgrade) your kernel.  Or enable substitutes.

How did you install Guix?  The installer script asks at the end whether
to enable binary substitutes or not: choosing no will require you to
build everything from source.

If you wish to enable transparent substitutes of pre-built packages from
the build farm, you can run this command:

  sudo guix archive --authorize < /var/guix/profiles/per-user/root/current-guix/share/guix/ci.guix.gnu.org.pub

Hope this helps!  :-)
