After today's upgrade to kernel 5.4.2 XFCE4 panels have disappeared.

Attempt to run panel configuration tool from XFCE4 produces error window:

xfce4-panel needs to be running for the preferences dialog to show. What output is generated when you run "xfce4-panel" in a terminal window?
Or to also get debug info:

How are you starting Xfce? Display manager (if so, which one), or xinit (what's in your ~/.xinitrc)?
Also:
loginctl session-statusecho $DBUS_SESSION_BUS_ADDRESSOffline
I am starting XFCE just hitting xfce4 right after login.
Suddenly, after several re-boots, the panel appeared.
Despite that the previous error remains:

After
pacman -S gnome-keyring
pacman -S libsecretI was asked to create keyring password.
Now, PAM - related error disappeared by unknown "application" -- is it normal?

Do you have a multi-monitor setup? If so, check your display settings to make sure that the Primary monitor is a valid monitor.
Offline
No, It's MacBook Air 2014, it's own monitor.
I checked monitor settings, and that's single laptop monitor.
I've found similar problems with people having extra monitors, but it looks like that's the different case.

It looks like you get that message if xfce4-panel is already running. Which makes sense. Is everything working okay now?
It might be a good idea to clear your saved sessions cache in case it got corrupted. Delete the contents of ~/.cache/sessions while not running Xfce.
Offline
I've cleared cache, but the error still persists.
$ xfce4-panel
(xfce4-panel:1172): xfce4-panel-CRITICAL **: 18:20:21.234: Name org.xfce.Panel lost on the message dbus, exiting.The system has panels now and works OK, but I've got another issue - when I'm leaving computer for a while, I return back, the screen is black, then hit arbitrary key, and instead of "Login" window I see black screen with the movable mouse pointer. I have to shutdown the system through the power key.
It might sound offtopic, but frankly I would change XFCE4 to some system-independent WIndows manager, in spirit of XFE file manager. What makes me unhappy with XFCE4, in particular, is its deep integration of Tsunar file manager, which is not possible to get rid of. The discussed sorts of things, apparenly connected with systemd integration, do not make me happy either.
