Matlab crashing when calling a python function with python external library imports

Hello,
I have a python file containing several functions which I would like to call from within MATLAB. I can call them without a problem from within the MATLAB console, however, if I would like to call the same functions from within a MATLAB script, it crashes giving me the following error:
