When I keep clicking on Splashscreen I get following error

[Mario777]

QApplication app(argc, argv);
MainWindow window(nullptr, argc, argv);
QPixmap pixmap(":Icons//Mysplash.jpg");
QSplashScreen splash(pixmap);
splash.show();
//app.processEvents();
Qt::Alignment topLeft = Qt::AlignLeft | Qt::AlignTop;
splash.showMessage(QObject::tr("Launch..."),topLeft, Qt::gray);
app.processEvents();
QApplication::setDesktopSettingsAware(false);
QApplication::setStyle("macintosh");
window.InitalSetup();
window.showMaximized();
splash.finish(&window;);
QTimer::singleShot(2000, &splash;, SLOT(close()));
return app.exec();

You should be calling processEvents() periodically while processing in side window.InitalSetup() method

... and running your program in your debugger to see where it is generating the unhandled exception.

The "nullptr" value passed on line 2 is begging to be misused inside the MainWindow constructor or methods.
The path on line 3 does not need two forward slashes.
You should, in general, copy and paste compilable code when asking for help. The second last line will not compile.
