crash on calling QWebEnginePage constructor

I have a WebEgineView embedded in dll which is called from external app(in my case photoshop).

During calling of setPage(new QWebEnginePage(this)); in child constructor of WebEngineView, my app crashes.
Crash happens in function QStringList QCoreApplication::arguments(), specifically on command : list << QString::fromLocal8Bit(av[a]);.
From some reasons QCoreApplicationPrivate instance has inconsistency in commandline arguments(argc:228, argv:"").

Call stack does not provide much information :/
