shiboken2 DLL Loading Problem

[Andy314]

Hello,
usualy I develop with in C++. Now will test the Python way in Qt.
Python 3.6 is installed in "D:\Python".

The script fails from the very beginning in this line:

from PySide2.QtWidgets import QApplication, QMainWindow

What can be the reason ?

This is shown in the "Application output"

\Users\weich\AppData\Roaming\Python\Python36\site-packages, D:\Python\lib\site-packages
Traceback (most recent call last):

I got PySide2 - 5.15.2

Try installing a previous version.

I have tested a lot of PySide versions but nothing helps.
Then in the source-code I found a hint to a libshiboken.dll. Under this topic you can find more in the net net.
The solution was Python 3.8.7.
