Gnome/Wayland won't start with dbus-run-session gnome-session

I've been using the command below to start Gnome on Wayland, and it has worked for a couple of years:

XDG_SESSION_TYPE=wayland dbus-run-session gnome-session

However, since updates a few days ago, that command gives me this error, and Gnome does not start:

*** Message: 15:21:50.930: Starting GNOME session target: gnome-session-wayland@wayland.target

** (process:965): WARNING **: 15:21:51.010: Could not get unit for graphical-session-pre.target: GDBus.Error:org.freedesktop.systemd1.NoSuchUnit: Unit graphical-session-pre.target not loaded.

My journalctl shows this:

Recently, there have been some similar problems mentioned in this forum, but none of the fixes for those problems have worked for me. Here are some notes:

• My /etc/nsswitch.conf is up-to-date

• My /etc/gdm/custom.conf has #WaylandEnable=False

• I can start gnome with gnome-shell --wayland (which I know is not recommended)
