Commit 4ff12d1de7cd617b791996ee7ca1240660b4c20e introduced that bug,
which was fixed in c9fbd40785a99e13a59d8e530830ce85220a9871:
https://issues.guix.gnu.org/56441
‘guix describe’ should show that you’re using a commit in that range.
The solution is to run ‘time-machine’ from a commit outside that range,
for instance with:
guix time-machine -- time-machine -C channels.scm -- whatever
:-)
