OSError: Error reading file

Hi, First I want to thank you for keeping up the development of this tool!

I have the folowing Setup:

Windows 10

(env) PS D:\XXX\XXX\citygml2obj-2.0> python --version
Python 3.10.0

(env) PS D:\XXX\XXX\citygml2obj-2.0> pip list
Package         Version
--------------- --------
contourpy       1.0.7
cycler          0.11.0
fonttools       4.39.4
kiwisolver      1.4.4
lxml            4.9.2
matplotlib      3.7.1
numpy           1.24.3
packaging       23.1
Pillow          9.5.0
pip             23.1.2
PyDecimal       1.0
pyparsing       3.0.9
python-dateutil 2.8.2
setuptools      67.7.2
shapely         2.0.1
six             1.16.0
triangle        20220202
wheel           0.40.0

I basically installed all packages that are listed in the requirements and used python 3.10.0. For "Decimal" I have used "PyDecimal" which should be fine.

I am trying to convert the following file:

https://geoportal.bayern.de/bayernatlas/?lang=de&topic=ba&bgLayer=atkis&catalogNodes=11&layers=WMS%7C%7COpendata_Auswahl_LoD2%7C%7Chttps:%2F%2Fgeoservices.bayern.de%2Fwms%2Fv1%2Fopendatagrid%7C%7Clod2%7C%7C1.1.1&E=689460.10&N=5337199.11&zoom=14

I am experiencing the following issue:

I have tried the following to resolve it:

added -v 1 and -p 1 flags

checked with CityDoctor 2.2.1

The tool didn't show anything in the GUI but gave this error in the console:
