Since this was an overran and not an overshoot..
Immediate questions are
Was the plane overloaded
Was the cargo secured, did it shift
Was there a mechanical failure.
Is it possible the pilot made a mistake? Yes, but given this wasn’t an overshoot, but an over ran, my first assumptions would be if human error it wasn’t the pilot failed to break. (Though it is possible)
Someone speculated that the flaps were in the wrong position for landing............
