Hm, it's similar to <https://issues.guix.gnu.org/52943>.

What kind of computer are you using? Is it aarch64 (64-bit ARM)?  

Please share the config.scm that causes the problem.

Also, please run `guix describe` in the same way you ran the command
that caused the error. For example, if you did `sudo guix system
reconfigure  ...`, then do `sudo guix describe`. Send the results and we
can try to debug it.
