The only pattern I've identified so far is that it happens within 2 hours of
resuming from hibernation. I'll try to narrow the time down.

I can tell you it's not related to the USB-C dock being plugged, since this
morning it happened without the dock being in use (hadn't been for over 60
hours).

I'll do that.
