Error 'NoneType' object has no attribute 'write' with .exe from .py

Hi,
first try publishing in this platform so here is my problem.
I have this code. And it is supposed to take a csv file with x000 lines and split it into x csv files with 1000 max lines. The problem is...
I turned it into an .exe and when i use it there's no problem, but when i try give it to another pc it doen't matter if i do it with zip, zip with password, or usb o any other method it always give the same error:
Error : 'NoneType' object has no attribute 'write':

Has this problem ever happend to anyone? if yes how to solve it? thanks in advance
