Internal Error - report

I have attached a folder of 2 logs one of which has an internal error. I was not able to capture a phot of the screen at the time, and the Tlog did not save for this- however the bin file did.

Arduplane 4.0.9
MP latest stable
Cube Black on standard carrier board
Foxtech Nimbus V2 Tilt motor

I was bench testing and was in Manual mode / changed to FBWA/B and back to manual - at which time MP stated internal error and entered failsafe mode, the Nimbus then went into Q-Mode and disarmed. I could not replicate the event.
