The problem is with the “guix” package, which used to give you an
environment containing guile-json@1.  This was changed in commit
2eb0628a423a36bc21777d7439885baa9a9a8e6d.  (If that’s not the culprit
perhaps it’s an old version of Guile JSON in your profile?)

Do “guix environment guix --ad-hoc guile-json” in the meantime.

Yes, the changes should be reverted.
