Quadcopter crash in position mode

PX4 1.13.2, cube orange/jetson xavier companion computer, quadcopter 4.9kg

Hi all, I've had a crash with my drone whilst flying in position mode with RC (without using the companion computer). I tried to switch back to manual but unfortunately could not save the drone anymore. Whilst analyzing the log files, I can’t directly find what might have caused the crash. I do see at the point where it went wrong a sudden jump in the roll and pitch set points, shortly after followed by one of the motors going to max thrust. The velocity controller seems to give some oscillations with a rather low damping. If there is anyone who might be able to shed some light on what might have gone wrong, it would be highly appreciated.
