    Hello, I have running Qt Project. But recently, I uninstalled Qt Creator and installed new version. Also, I updated the Microsoft Visual Studio 2017 to latest version. After update, I can still the project with MSVC compiler, but I cannot run the Qt GUI application. It tries to run, but it exits with code 1073741819. Please help.

    any chance you have old intermediate build files left?
    Try deleting the build folder and run a clean build again.

        did you also rerun qmake beforehand?
        (clean -> rerun qmake -> build)

            So, how about posting a stacktrace?
            Guessing only get's us so far.

                try updating your Intel graphics driver to the latest version

                Also what graphics chip do you have exactly?
                Did you specify any OpenGL related properties for your application?

                    @raven-worx . I have Intel HD Graphics 630 and Nvidia Quadro M620. No, I am not using any OpenGL. I do have a QtQuick Widget.

                      @raven-worx. Thanks, you are right. It is Intel graphics driver issue.

                        did you solve it with an driver update?

                          @raven-worx . Yes, it is already resolved. But, I do not understand which widget is using OpenGL.

                            QQuickWidget (=> QML)
                            Unless you explicitly tell it to use the software rasterizing backend.
                            e.g. either via code QQuickWindow::setSceneGraphBackend(QSGRendererInterface::Software); or via environment variable QT_QUICK_BACKEND=software
                            (before QApplication instantiation)
