if your QWebEngineView has a parent widget, it is automatically destroyed whether the parent widget is destroyed.
Now, your stack shows a QEnableSharedFromThis. This is for classes that are created using a QSharedPointer and that need to be able to recreate a QSharedPointer from them. It might means that you have somewhere a "delete toto;" called on a SharedFromThis class. This might explain the crash.
