Weird Error with Python 3.6.2 - running bat file won't work

Running the same script in bat file by launching it won't work, but if I copy the command and paste to an open command prompt, it will work. the command is "C:\Program Files\Python36\python.exe" -path-to-script- -params "paramvalue"

Traceback (most recent call last):
