System shutdown on its own (related to timedated?)

[canadaduane]

How did you upgrade to 22.04? (Fresh install / Upgrade)
Upgraded from 21.10

Related Application and/or Package Version (run apt policy $PACKAGE NAME):

I'm not sure.

Issue/Bug Description:
My system shut itself off suddenly. I'm looking at journalctl logs to see what may have caused it:

I'm seeing hundreds or thousands of messages in journalctl like this (more than appear to fit in the log? or perhaps I just don't know how to see what's before "line 1" of journalctl output?):

pop-os gsd-datetime[2440]: gweather_location_unref: assertion 'loc != NULL' failed

I also have a message that says:

Apr 13 10:40:35 pop-os systemd[1]: systemd-timedated.service: Deactivated successfully.
░░ Subject: Unit succeeded
░░ Defined-By: systemd
░░ Support: http://www.ubuntu.com/support
░░ 
░░ The unit systemd-timedated.service has successfully entered the 'dead' state.

Steps to reproduce (if you know):

I'm not sure what caused this, but I'm betting the != NULL assertion shouldn't be happening.

Expected behavior:

The system should not shutdown on its own.

Other Details:
I was running libinput debug-events at the time in a background terminal, which is a monitoring tool for the trackpad. I wonder if it's somehow related...
