Are you using any accessibility tools?
(In reply to Nate Graham from comment #1) > Are you using any accessibility tools? audible bell I didn't manually enable anything, in theory, it's as it is by default in the installation, but checking I found the audible bell option enabled. However, I disabled it to test and the error remained.

Looks like essentially same issue as Bug 426047, but in a different app. Perhaps a Qt bug...

Created attachment 162375 [details] Crash report Same here. The crash is always reproducible when changing tabs. Weirdly, it only happens on my tablet and it works fine on all my other devices. Linux: KDE Neon KDE Plasma version: 5.27.8 KDE Frameworks version: 5.110.0 Qt version: 5.15.11
I found an upstream bugreport about this: https://bugreports.qt.io/browse/QTBUG-84858 . The marked bugreport is closed but the fix mentioned there is incomplete and things can still crash. That said, I do now know how to workaround it.
A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-systemmonitor/-/merge_requests/235
Git commit 5f1e762a8b93e36bae7b5d1e856b04682d4aa66c by Arjen Hiemstra. Committed on 26/10/2023 at 16:32. Pushed by ahiemstra into branch 'master'. Workaround QTBUG-84858 In certain cases destroying a table cell will end up calling a virtual method incorrectly. This was partially fixed upstream but only when the Accessible attached object exists. To workaround the upstream bug, ensure we create an instance of the attached object. As a bonus, this also means we now set the right accessible role for table cells.
