You need python qt webengine 5.15.6 for use in qgis. See
https://www.riverbankcomputing.com/static/Downloads/PyQtWebEngine/ChangeLog-5.15.7.dev2405031852

The required change is "Allow Qt.AA_ShareOpenGLContexts to be specified
before a
 QCoreApplication is created to allow PyQtWebEngineWidgets to be
 imported.".

I'd file a bug for your distro and request and update.
