    Description

      The following minimal example crashes as debug build with error:

      [0227/082330.153:FATAL:com_init_check_hook.cc(153)] Check failed: false. CoCreateInstance appears to be previously patched. (90 90 90 90 90 e9 f0)
      
      #include <QApplication>
      #include <QWebEngineView>
      
      
      int main(int argc, char *argv[])
      {
          QCoreApplication::setOrganizationName("Org");
          QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
          QApplication app(argc, argv);
      
          QWebEngineView view;
          view.resize(800, 600);
      
          view.show();
          return app.exec();
      }
      

      The release build is fine.
