setUrl(QUrl causes a core dunp in Arch Linux

I have the Pyhton code below using a Python virtual environment in Arch Linux, running KDE Plasma 5 Desktop. When the code is executed the main window displays and briefly a smaller white rectangle appears but the QWebEngineView is not visible. I have checked that it is visibel and enabled. When Ilooked further into this I ascertained that the line         self.browser.setUrl(QUrl("https://www.google.com/")) results in a core dumps like this:
