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 (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
