Error trying Tutorial for creating new Parameter

[Amaya001]

Hello,
I'm new to using Python with openLCA and tried to create a Parameter via the Python script. I used the code from ( https://github.com/GreenDelta/openlca-python-tutorial/blob/master/examples.md ) for creating a new Parameter and got the following Error. I already searched for the problem but couldn't fix it. I already tried the following: reinstalled openLCA, installed openLCA via the zip folder, installed an internet version of the -3.dll and put it in the folder, and checked the write access.
I don't know what to do. The example script for the "Hello from Python (Jython)!" Dialogue worked well.
Hopefully someone can help me.
