QT Web Engine freezes when calling any method from main.cpp

aphi

Hello,
now I have another problem. When I try to load another URL from main.cpp with the overload method, the whole application freezes and crashes. What am I doing wrong here? I have done the same like described in http://doc.qt.io/qt-5/qtqml-cppintegration-interactqmlfromcpp.html
Code:
main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QtQuick/QtQuick>
#include <QtWebView/QtWebView>
#include <QtWebEngineWidgets/QWebEngineView>
int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);
    //QtWebView::initialize();


    QQuickView view;
    view.setSource(QUrl("qrc:/main.qml"));
    view.show();
    QObject *object = view.rootObject();
    QQuickItem *item = qobject_cast<QQuickItem*>(object);
    QWebEngineView* rect = item->findChild<QWebEngineView*>("view");

    QVariant msg = "http://google.de";
    rect->setProperty("url","http://google.de");
//or
rect->load(QUrl("http://google.de"));
 



    return app.exec();
}

main.qml

import QtQuick 2.6
import QtQuick.Window 2.2
import QtWebEngine 1.0
Item {
    visible: true
    width: 1500
    height: 800
   // title: qsTr("CENSORED")
    WebEngineView {
        id: view
        anchors.fill: parent
        url: "CENSORED"

        objectName: "view"
   
    }

}

@aphi QWebEngineView* rect = item->findChild<QWebEngineView*>("view"); you never test the result here. It can be null and if it was null it would crash.

Can you run this in a debugger and give a backtrace of the crash?
