This is likely what happened. The software hit an invalid state that defaulted to disengaging the autopilot feature. Likely hit an impossible state as the camera could no longer piece the “wall” parts of the road with the actual road as it got too close.
Likely an error condition occured that would happen in the same way if an object suddenly covered the camera while driving. It would be even more concerning if the autopilot DIDN’T disengage at that point.
