    Description

      QQuickComboBox::setModel() does an unguarded qvariant_cast on the previous value.

      This will crash if you delete the previous model, then subsequently call setModel(newModel).

      See https://codebrowser.dev/qt6/qtdeclarative/src/quicktemplates/qquickcombobox.cpp.html#1021
