An error has occurred while executing Python code - GQF

[030Skript]

Hello all,

I wanted to use the GQF module for my master thesis. While trying to start the tutorial, I encountered the following problem on 2 different computers (Windows 10). After installing UMEP (4.0.2) for QGIS (3.34) and downloading the following packages, I prepared the data sources and clicked on "Prepare input data via data sources" and after a few seconds I got:

An error has occurred while executing Python code

So, now that I've tried it on my PC and have the same problem. I hope you guys may have a solution to this issue? After pressing the button once, I can no longer use it and have to restart the Plug-In.
