Solved QtCharts leads to crashing of application

[Leon_2001]

Hi everyone,

import QtQuick 2.12
import QtQuick.Window 2.12
import QtCharts 2.3

Window {
    visible: true
    width: 640; height: 480

    ChartView {
        anchors.centerIn: parent
        width: 400; height: 400
    }
}

does not work. I also tried several other things (with ApplicationWindow, more content etc.).
It just crashes.

Error: EXC_BAD_ACCESS (SIGSEGV)

I did link to charts in my project file.

It is somehow related to Window/ApplicationWindow/QApplicationEngine. The examples of QT are working and use QQuickView.

Anyone an idea what is going on here?

I found the solution to the problem. I uses QGuiApplication instead of QApplication, I overread that I need this.
