[Python] df1py3 import not working in debian linux

I have Ubuntu and Raspberry Pi OS machines that I am trying to use to talk with Allen-Bradley PLCs using df1 protocol. There is a python import aptly called df1py3 that can communicate with these PLCs, and is capable with working on windows (I have tested it successfully on Windows 10). However, when I try it in both Linux distros, I get a helluva error message that seems to amount to: 'you can't talk over the serial port.' However, I am able to communicate using the standard serial import in python, so the serial ports do work. I've spent quite a bit of time on this and am at a loss, so any help would be greatly appreciated. It shoudl be noted that I am using a python virtual environment to keep from conflicting with the preinstalled python config. Here's the code and the error:

Tried:

1. Change serial port permissions
2. Change serial cable
3. Change computer (Raspbian to Ubuntu)
4. Using standard serial import (worked, so i know serial communication in general works)
5. Change PLC I was speaking to (Micrologix 1200 to SLC500 with 03 CPU)
6. Go to dependencies and find what was messing stuff up
7. Posted this to stack overflow
