@milan said in Qt App runs and exits with crash 1073741819: 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)

@jack9603301 Good to hear. Happy code :)
