I don't know of a fix, but Guix is tracking this issue here:
https://issues.guix.gnu.org/issue/57878

I have been unable to upgrade Guix due to this issue.  In my case it
locks down my whole system with endless compilation processes.  I
wouldn't mind seeing native compilation disabled until upstream
improves the experience, but it's been decided that native compilation
is staying on. So, we're stuck on an old Guix until there's a
solution.
