Screen hangs on "Waiting for Klipper..." #14

I am running into an issue where the status bar will fill up and then hang on the "Waiting for Klipper..." Screen. When I run the program, it will establish the connection and then while the status bar is filling up, the program will repeatedly print Exception 431, and then once the bar fills it will repeatedly print the following:

Exception 431
Unexpected data received: 0x1c
Unexpected data received: 0xff
Unexpected data received: 0xff
Unexpected data received: 0xff

My device is a Raspberry Pi 3 B running 64-bit Mainsail OS. The web interface still works, it is just the screen itself that is having issues. The issue occurs both when I use a USB to UART converter and when I use the UART pins on my Raspberry Pi. I have looked into other issues related to the problem I have, and none of them seem to fix my issue; the changes that I have made aside from what is said to do in the guide are the changes proposed in #6 and replacing the device path to the USB to UART device with its entry in /dev/serial/by-id/, neither of which had any effect on the issue.
