Hey guys,

I only a junior in python, but I am trying to start 2 process that listen udp/tcp port. Basically I want to use multiprocessing for "tcp_process" and "udp_process".
I've found multiple stackoverflows on this, but I have no Idea how to adjust my code to make this run succesfully. I understand that my arguments are not pickleable. How do I make it pickable on Windows?
i get below full trace back.
