According to sentry, this issue has almost entirely disappeared in the wild; lowering priority despite the historically high number of older duplicate reports.
Comment 18 DeeHY 2025-03-22 03:03:32 UTC 
In fact, this error has always existed.

> Crash log on KDE Neon running 6.4.1

Thanks for the new crash log. I don't see qobject_cast in this backtrace, or ShellCorona::createWaitingPanels. The Sentry report indicates the last event related to ShellCorona::createWaitingPanels was 2 months ago in 6.3.4.

Based on this backtrace, it looks like your crash is bug 500044.
Comment 23 Sören Jonsson 2025-07-10 07:20:23 UTC 
The crashes occur randomly, so it is hard to find the reason. This can be mitigated by touching the keyboard before touching the mouse.
