SUMMARY
From the system journal (see attachment), I can see that various KDE components (kded, plasmashell, etc.) die with the "The Wayland connection broke. Did the Wayland compositor die?" message. So it looks like kwin begins shutting down too early, preventing these components from cleanly shutdown.

This causes kded unable to save bluetooth state on shutdown.

STEPS TO REPRODUCE
1. reboot
2. journalctl -b -1
3. search for "Logout"

OBSERVED RESULT
Plenty of "The Wayland connection broke. Did the Wayland compositor die?" errors a few screens below.

EXPECTED RESULT
No such errors.
