Did you intend to send this to #974985 "gnome: logged out after screen
lock", rather than to #974987 "gnome-control-center: blank screen option
in two menu entries"? It looks more appropriate for #974985.

Is #974985 something that happened once but not reliably, or does it happen
every time you let the time-based screen lock happen?

Are you using Wayland or Xorg?

Please try disabling all GNOME Shell extensions. If that resolves this,
then it's a bug in one of the extensions, most likely the window list,
and we should reassign #974985 to that package.

Another thing to try would be to upgrade gnome-shell and libmutter to
the versions from experimental, which contain most of the changes that
will be released as 3.38.2 later.

As far as I can tell from your log, either GNOME Shell, Xwayland or
Xorg crashed after this point - although I would have expected more
messages to be logged. Please try looking at the corresponding time in
the systemd journal or /var/log/syslog, which might provide more detail
(not all messages go into /var/log/messages).
