1. If you are using one single layout then go to layouts editor and activate mode "Single layout at all cases" and try again
2. proper way to report crashes https://userbase.kde.org/LatteDock/HowToReportCrashes
3. if you are using wayland then multiple layouts mode under wayland can not be closed properly yet because there is no wayland way to tell apps to close themselves properly. If you still need multiple layouts mode then you need to close Latte before logging of wayland session.

1. Ok, Latte Dock would crash before I can get to the layout editor. No cache exists in ~/.cache/*. Latte works when I run `latte-dock --single` in the terminal, but it seems like the layouts were reset to stock.

2. My apologies, I forgot to attach the traceback (issues submitting it with DrKonqi). I'll use ddd as directed for future reports. Due to the reset in 1. , I can't trigger the crash again.

3. These crashes occurred in X11. Wayland in general is far too unstable for daily use (IMO).

the crash is from applet window buttons that is not ready for Plasma 5.23,

Ok, I can confirm that. Latte crashes as soon as I add the 'applet window buttons' widget. Sorry for the noise.
