Well, at least we know that's the problem. Could you set

[debug]
Enable=true

in /etc/gdm/custom.conf, and restart gdm.service and try to log in again? It will fill the logs with lots of information, but it could tell us where the exact problem is.

Also, when using journalctl please use the -b flag, so only the logs from the last boot are printed.

Regards.
