Updated Firmware to 0,52.0 and not app causes Bus Fault

As a test which I forgot to do yesterday I ran the example from: Arduino Uno Q and Bridge Tool: any samples and documentation? - UNO Family / UNO Q - Arduino Forum and it worked so not sure what is going on or where the issue is yet

@manchuino is there some sort of tests you want me to add to see whats going on?
