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.

https://guix.gnu.org/manual/en/html_node/Keyboard-Layout.htmlI have
found solution. Actually bug was caused by using simultaneously two
snippets from manual.
One from keyboard layout section
https://guix.gnu.org/manual/en/html_node/Keyboard-Layout.html

(operating-system
  ;; ...
  (keyboard-layout (keyboard-layout "tr"))  ;for the console
  (bootloader (bootloader-configuration
                (bootloader grub-efi-bootloader)
                (target "/boot/efi")
                (keyboard-layout keyboard-layout))) ;for GRUB
  (services (cons (set-xorg-configuration
                    (xorg-configuration             ;for Xorg
                      (keyboard-layout keyboard-layout)))
                  %desktop-services)))

One from X Window section
https://guix.gnu.org/manual/en/html_node/Keyboard-Layout.html
(operating-system
  ;; ...
  (services (cons* (service slim-service-type (slim-configuration
                                               (display ":0")
                                               (vt "vt7")))
                   (service slim-service-type (slim-configuration
                                               (display ":1")
                                               (vt "vt8")))

After I have moved the keyboard-layout option to slim-configuration,
the error disappeared.
Still, this is a bug I believe.
Please let me know if additional info still needed.
