I have a strange freeze in QGuiApplication that I could reduce to a minimum example.

• Add QWebView to your project
• Add QGuiApplication to your project and make a minimum HelloWorld example

When I start this application it freezes in the constructor of QGuiApplication. The stacktrace shows this line where the freeze occurs:
OpenGLTester::testDesktopGL() Line 375

if (!MakeCurrent(dc, context))
    goto cleanup;

When I remove the import 

#include <QtWebView> 

the freeze doesn't occur.

Also with Qt Version 6.5.3 the freeze doesn't occur even with QWebView active

I had the chance to try it on a different machine with another NVidia card. It happens there too. But both machines have the same driver version. So the two machines where I could test it are:

• NVIDIA GTX 1050 with Driver 546.01
• NVIDIA GTX 1650 with Driver 546.01

I will attach the minimum example on this issue. When the freeze occurs the console will print out only

Before QGuiApplication app(argc, argv)

and freeze afterwards
