I got the same issue since V3:

Same here. No clue what's causing it. First error line is less than helpful.

Fixed it.

In MQTT.py:

Line 156 and beyond:

        topic = Data['Topic'] if 'Topic' in Data else ''
#        payload =  Data['Payload'].decode('utf8') if 'Payload' in Data else ''
        payload =  Data['Payload'].decode('latin-1') if 'Payload' in Data else ''

Changed decoding from utf8 to latin-1.
