    Description

      Author of RSS Guard here.

      https://github.com/martinrotter/rssguard

      My application is built by Github actions. When built with Qt 6.6.3 (or any older version). The app works as expected.

      When built locally or via Actions with Qt 6.7.0, app crashes somewhere inside QtWebEngineCore module.

      Specifically when calling this line:

      auto* xxx = new QWebEngineProfile("rssguard", this);
      

      This line is basically called inside QApplication-subclass constructor.

      The bug only presents itself on Qt 6.7.0 and only on Windows. The exact same codebase works fine with older Qts. The above code is called from main thread.

      I attached the crashdump.
