[PyQt] QtWebEngineWidgets doesn't work on Windows and Linux only Mac

[Starglider Developer]

HI,
need to insert a browser in a form to show HTML/CSS/JS,
a few years ago I did it with QtWebKit in python 2.7 and PyQt5
but QtWebKit was removed from PyQt5 and replaced by QtWebKitWidgets.

The problem is that in linux (Debian 9.6 64 bit) it gives a
error:QOpenGLShaderProgram: could not create shader program!
and doesn't show nothing,
in Windows 7 32 says it can't import QtWebKitWidgets but in Mac it works
fine (3.7/PyQt5 5.11)

I try several versions of python and PyQt5 in windows 32 and 64 bit, and
was unable to import QtWebKitWidgets

Any idea?
or there is another way of showing HTML/CSS pages with PyQt5?

Thank in advance
