So apparently I see a session opened here so logind itself seems to
work as expected.

But looking closer in the logs you posted, I see:

gdm3][4091]: pam_systemd(gdm3:session): Failed to create session: No
such file or directory

This is a bit puzzling me. Could you please try to reinstall the
libpam-systemd package maybe.

Also in the logs I see the following warning/error:

The value for the SHELL variable was not found the /etc/shells file

Are you using some fancy shell for your user?
