Error when trying to run code based on PysimpleGUIqt

Question

I am trying to run a code using PysimpleGUIqt but it gives following error:

I have tried to install windows but getting following error:

If I try to install window it will be installed but error remains. I even installed pyqt5 but nothing changed. Have no idea how to solve it. The whole code is attached below for your reference which is originally taken from here:

EDIT:

Based on suggestions made by @Robert Davis I have tried to modify %QT_PLUGIN_PATH% but there was no such path in my system environment.

Answer 1

It looks strange but I just made this change in the preamble:

import PySimpleGUI as sg

Instead of:

import PySimpleGUIQt as sg

And it is all well now.
