@Chocobo1 I can't reproduce this though with Qt 6.2.4/Qt 6.3.2/Qt 6.4.3 ??! reference builds -> https://github.com/xavier2k6/qBittorrent/actions/runs/5037443889

Indeed. #18841 could be right about it. However the curious case is Qt5 from appveyor. AFAIK that Qt5 is quite old and hasn't updated for some time yet it crashes too.
However the curious case is Qt5 from appveyor. AFAIK that Qt5 is quite old and hasn't updated for some time yet it crashes too.
Have you managed to test master with any newer Qt5 versions Qt 5.15.3 -> Qt 5.15.9 than AppVeyor's provided Qt 5.15.2?
I've checked the last AppVeyor build available for backport under the 4.5.x branch & don't experience the silent crash so it seems to be a master issue.
Could there be some Qt 5/6 conditional/define overlooked or not in place??
For reference Qt 6.5.1 also silently crashes.

The steps of saving stuffs should be performed in the cleanup().
I made a patch and it seems to work. https://github.com/brvphoenix/qBittorrent/commit/7aaf3da71b02fe447bd525a772525475129274a4

Could you elaborate what is the fundamental difference in the shutdown flow that fixes the problem? Why did you extract cleanup methods from destructors of some classes? Were they the remaining parts of their destructors that cause the problem by being called in the previous place?
Could you elaborate what is the fundamental difference in the shutdown flow that fixes the problem?
This has been explained in #18841. The reason of crash may be at https://doc.qt.io/qt-6/qobject.html#dtor.QObject.
Deleting a [QObject](https://doc.qt.io/qt-6/qobject.html) while pending events are waiting to be delivered can cause a crash.
Why did you extract cleanup methods from destructors of some classes?
I delete all the objects in qapplication destructor. According to qapplication::exec, we should use aboutToQuit() to ensure the data will not be lost because unexpected shutdown.
Were they the remaining parts of their destructors that cause the problem by being called in the previous place?
I can't figure out what exactly is causing this crash. I‘m using the qbittorrent-nox, and the crash appears at this line. https://github.com/qbittorrent/qBittorrent/blob/a35dbc6df7cdae99efd5d097527fc393e03c6449/src/app/application.cpp#L1259
I have no crash on both Windows and Linux after updated Qt to 6.5.1.
I still did with Qt 6.5.1 previously.....I'm a few commits behind master branch so will test again......

Strange... It looks like I made a mistake after all. At least on Windows, it still crashes. I'll double-check on Linux tomorrow.
@glassez Ya, it still silently crashes with Qt 6.5.1
https://github.com/xavier2k6/qBittorrent/actions/runs/5145785713
I can reproduce this issue with appveyor builds which was using Qt 5.15.2 so it isn't limited to Qt 6.5.
Ticket title changed.
