Probable cause
The flight team's failure to program the UAS with flight-tested parameters that could tolerate the high density altitude and tailwind conditions encounted during the flight, which resulted in two undershoot approaches, and the existence of an undiscovered software anomaly that resulted in a momentary loss of control and overshoot of the final approach course, followed by a steep descent and subsequent collision with a light pole.
