Hi @Balint Takacs,
I too encountered this error, the workaround that worked for me was to reinstall the "matlabengine" module. Kindly ensure that you need to run following command in this directory "matlabroot\extern\engines\python".
pip install matlabengine
I have revised and executed your script without any errors. I have saved the model and attached it for your reference.Kindly refer to the below image for the revised script.
