kwin_x11 crash coredump
After a kwin crash and auto-restart of plasmashell the window rules are not restored. Window rules have to be changed and re-applied through settings to be party restored. The shortcut-access rules are not restorable. As a result advanced workflows through window rules are not usable anymore.
STEPS TO REPRODUCE
1. produce a kwin crash
2. retry keyboard shortcut defined in window rules
3. re-apply window rule settings (now rules party in effect; shortcuts still not working)
Keyboard shortcut for window access/focus not working anymore
All window rules restored into effect after plasmashell restart.
I cannot fully reproduce this. After crashing kwin (kill -SEGV), it is auto-restored and most rule settings re-applied (for instance, the virtual desktop rule or color scheme).
It's difficult to assure which of them are restored or not because they are checked and applied individually.
The shortcuts rule though is not restored just as you describe.
Which ones did you notice that are also not restored?

Right, the shortcut rule is my main observation. Also I belief that I noticed different positioning from my primary towards my secondary display. But the main issue is about the window shortcut access rule.

Workspace: Better check of registered client shortcuts
Do not discard a shortcut immediately when it is already registered
in KGlobalAccel, because there could be possible dangling shortcuts
if they weren't properly cleaned-up (ex. after a crash).
Instead we delay the check for conflicts with other client shortcuts
to the second loop, which we know is up to date.
