The error caused by the GPIO.cleanup() function didn't seem to be doing anything bad at first, but I later noticed some of the output pins get set to high after exiting the program. This can cause devices such as LEDs and motors to turn on when this happens. To avoid this, make sure you install the rpi-lgpio library as a system package, not as a PIP package. I've updated my written guide with this suggestion.
