Bug Description

I see the following assert failure when closing Mixxx built with Qt6 (either by closing the window or via File -> Quit).

fatal [Main] ASSERT failure in WWaveformViewer: "Called object is not of the correct type (class destructor may have already run)", file /usr/include/qt6/QtCore/qobjectdefs_impl.h, line 119

I can't reproduce this on macOS. Does this happen every time? And with any waveform type? Does it also crash when changing skin?

I can't reproduce this on PopOS 22.04 although I seem to recall this crash at some point last year.
Looks like this was fixed by #12314 indeed. Shall we close this issue?
