Not sure how to fix this, randomly occurred, 3 transceivers now fixed in this state, state wont change even with library example code uploaded.

Are you sure that the serial baud rate matches the sketch? Does a similar thing happen if you skip the LoRaWAN stuff (i.e. put a while(1); infinite loop somewhere after the "starting" print? Or maybe try adding some Serial.flush(); calls to ensure output is printed before continuing to see how far it comes? What hardware are you using?
