Flying Wing: Massive roll/pitch setpoint switching from Manual to Autonomous mode; caused crash

First time posting here, so forgive me if I leave out some crucial information.

The issue I’m having is that when switching from a manual mode to an autonomous mode the pitch and roll setpoints have a step change to very large values. I have experienced this on two flying wings (1 home built, 1 E-flight Opterra). The first incident led to a crash. The second time I made sure I had sufficient altitude before testing. Below are the details and flight logs.

Any help is appreciated. I don’t know if this is a potential issue with the hardware (Orange+), the PX4 v1.14 firmware, or if it is specific to the flying wing airframe selection. Both aircraft flew fine in manual modes (manual and stabilized) before the incidents.

I am afraid I have no idea how PX4 works and my cheeky response would be fly with a better firmware (Ardupilot)

Lots of warnings in the data.
