I do not see obvious problems. What might be inspected more closely:
May 05 14:09:14 debzit systemd[711]: Stopping D-Bus User Message Bus...
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If it is the bus shared with ssh connection than it may be an issue,
however it is for systemd unit, real process may be running independently.
Perhaps there is a specific command, but at leas you may compare
env | grep -i bus
from ssh and from GUI sessions. Output may be like
DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus
May 05 14:09:14 debzit gvfsd[14302]: A connection to the bus can't be made

Why it started again from the same systemd user session if it is logout?
I would compare with logout messages when there are no ssh connections.

Likely it is completion of closing PAM lightdm session. I do not
remember if it is possible to increase PAM verbosity to get a log entry
when PAM close session are called. However systemd may perform actions
in parallel, so attributions of log entries to specific actions may be
ambiguous.
