Unable to load psycopg2 library

Describe the problem
Unable to load psycopg2 library
I don't know if this is a problem with Python or JEP. When I execute import psycopg2, an error occurs

jep.JepException: <class 'ImportError'>: cannot import name 'encodings' from 'psycopg2._psycopg' (D:\HXL\apps\python\3.13\Lib\site-packages\psycopg2\_psycopg.cp313-win_amd64.pyd)
	at D:\HXL\apps\python\3.13\Lib\site-packages\psycopg2\extensions.<module>(extensions.py:50)
	at D:\HXL\apps\python\3.13\Lib\site-packages\psycopg2\__init__.<module>(__init__.py:80)
	at <string>.<module>(<string>:1)
	at jep.Jep.exec(Native Method)
	at jep.Jep.exec(Jep.java:384)

Environment (please complete the following information):

• OS Platform, Distribution, and Version: windows
• Python Distribution and Version:3.13
• Java Distribution and Version: 21
• Jep Version: 431
• Python packages used (e.g. numpy, pandas, tensorflow):psycopg2

Usually problems related to importing 'encodings' are related to PYTHONHOME or venv activation. If you are not using venv then ensure PYTHONHOME is set correctly for your python installation. If you are using a venv you should usually ensure that PYTHONHOME is not set but the venv should be active before starting your java application.

If you have multiple python installation you should double check that jep was built and loaded for the same python installation where psycog2 is being loaded.

I have configured PYTHONHOME, but it is still the same error

Is it possible that there is a reason for the slippery Pyd
