That's the same issue reported earlier, right?  Did you try your config
in a VM ?

I just tried running a VM produced with 'guix system vm
~/src/guix/gnu/system/examples/desktop.tmpl', and then issuing:

--8<---------------cut here---------------start------------->8---
/gnu/store/x03nwvky3lil1qn9a5gxhazy3qzrmhwb-run-vm.sh -m 4G
--8<---------------cut here---------------end--------------->8---

And it works (it defaults to Wayland), but it's slow because of the lack
of hardware acceleration.

To try with GNOME Boxes, which will configure hardware acceleration by
default, I generated a disk image with:

--8<---------------cut here---------------start------------->8---
guix system image --image-type=efi-raw ~/src/guix/gnu/system/examples/desktop.tmpl
--8<---------------cut here---------------end--------------->8---

Which gave me a gigantic 9 GiB file, which I copied e.g. to:

--8<---------------cut here---------------start------------->8---
cp /gnu/store/qpfzrzzhajiv5gwd8fmicw60y253i7zj-disk-image \
   /scratch/virtual-machines/gnome-boxes/images/gnome-uefi.raw
--8<---------------cut here---------------end--------------->8---

And loaded up in GNOME Boxes (installing from a file).  To make sure you
can select a UEFI bootloader in GNOME Boxes, you need very recent
libosinfo data, so run this first:

--8<---------------cut here---------------start------------->8---
guix shell osinfo-db-tools -- osinfo-db-import --user --nightly
--8<---------------cut here---------------end--------------->8---

I hope this helps troubleshooting on your side.  Make sure to use the
desktop.tmpl template to avoid any other problems that may be only
apparent from your own config at first, and do try Wayland as X11
support is being removed from GNOME anyway.
