HELP with the log analysis for drone crash

Today I tried to fly my Hexa with a pixhawk cube but before even taking off in auto mode the drone flipped itself sideways and ultimately flipped upside down. that was scary. I have been trying to check logs to make out the sense of what actually went wrong.
I think the RCOUT value for Roll and Yaw seems pretty abnormal to me.

For flight mode, that I used: LOITER, AUTO & RTL
As soon as I switched to AUTO mode the hex raised its throttle and instead of gaining altitude it rolled right side and ultimately flipped the drone :worried:
I used the motor emergency stop switch to stop the motor using channel-7 but there is no data of channel-7 switching in RCIN c7.
here is the log file.00000056.BIN (255.8 KB)
