Arduplane, Dead Roll after Switch to Auto Mode


I’m using Matek F405W and use Chibi OS Arduplane. I inserted SDCard and logging properly.

I’m often use my HDWing to do mission and succeed without any problem. Yesterday i uploaded the waypoint data without any error and it could auto takeoff but when execute the 3rd point, the plane suddenly spin and could not be controlled. I tried to switch Manual and RTL but unlucky the plane crash.

I’m confused why this issue happen and what best practice before we upload the mission ? should we clear the previous data ? and how to do it ?

Please advise. Thanks
