Thanks.  Given this, and the lack of similar reports from others, my
guess is that you hit a non-deterministic Guile bug, possibly the same
one as <https://bugs.gnu.org/46879> (Non-deterministic failures while
building Guix with Guile 3.0.5).

If the problem happens reproducibly on that one VM only, that suggests
that the bug might have led to a corrupted store item, i.e. a store item
containing a .go file with bad code.  If so, running "guix gc" might be
sufficient to clear the corrupted items.

     Regards,
       Mark
