Python _PythonStandaloneApplication object has no attribute 'TheApplication'

Hi Zemaxers

 I am trying the python sample code of ZOS-API (as attached below). But it does not work at the first step.

https://support.zemax.com/hc/en-us/articles/4403605141267-Generate-the-executable-in-Python-for-ZOS-API-User-Extensions

The error shows as below

AttributeError: 'PythonStandaloneApplication' object has no attribute 'TheApplication'

(after checking the zemax install root , I guess it has something with 'TheApplication'  attribute)

Environment

python 3.10

PyCharm Community Edition 2022.1

Ansys Zemax OpticStudio 2024 R1.03

pythonnet version 3.0.3

Attached code 

What I have done:

checked the address below, it is correct

Could you give me some advice on this issue?

Thank you
