How to Rescue GuixSD when guile and guix arebroken?

[znavko]

Hello! I want to ask novice's question, cause the first I want, having trouble, is to re-install GuixSD, but rescue with USB-stick is faster.

I have for second time a bug described here: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=31162

Both times, as I think, it happened this way. I run `guix pull`, switch off notebook while it is running (just a mistake) and then I run again `guix pull`, it works, but gives the errors.

Here it is log I copied from terminal: https://pastebin.com/7c06ER7v

Guix is not working at all.

# guix gc -R $(readlink -f ~/.config/guix/latest)

I reported this bug to Bugs Maillist. But for future want to ask how can I rescue broken system booting with GuixSD USB-stick?
