bug#55488: GDM, GNOME: Can't start desktop session after upgrade |

I'm using the Guix system. After upgrading it to recent versions of Guix (e.g.
guix 1110479), I can't access the GNOME desktop. The problem is also present
when creating a virtual machine with the same configuration file used for the
real machine (guix system vm config.scm).
STEPS TO REPRODUCE
I guess these:
1. guix pull --commit=1110479d2d4dc69fc66eadb4a6c24ca2f13afa93
2. guix package -m MANIFEST.scm
3. sudo guix system reconfigure CONFIG.scm
4. sudo reboot
5. Log in in GDM
(MANIFEST and CONFIG available on request if necessary)
EXPECTED RESULT
After a few seconds, the GNOME desktop shows up, and you can start working
normally.
UNEXPECTED RESULT
In the real machine, only a black screen appears. After hours, there is no
change. There is no mouse pointer or any indication that the desktop has loaded.
In the virtual machine, you see a black screen and the mouse pointer appearing
sometimes and then disappearing. After a minute, you are taken back to the log
in screen, which now behaves erratically: when you click on your user to log in
again, it shows the username input box, and, once you move the pointer to enter
your username, the view is changed back to the list of users. The same happens
everytime you try to log in again.
ADDITIONAL INFORMATION
The most recent system generation where this problem does not occur for me is

WORKAROUND
Personally, I choose one of these options:
1. Use Sway as an emergency desktop (which is always in my system config file).
2. Roll back to a generation of the system that works (e.g. guix ab98b51e).
This usually requires to roll back to a previous generation of the user profile
as well to avoid other errors when logging in to GNOME.
