Some very strange error messages, not just AOA offset:

At 05:38:46 and about 200 ft radio altitude, the Master Caution parameter changed state. The
First Officer called out Master Caution Anti-Ice on CVR. Four seconds later, the recorded
Left AOA Heat parameter changed state.

Edit: I thought it was not possible to engage the autopilot while there was AOA disagree, but it seems that it did happen for a short interval.

Edit: The sequence in this crash was slightly different, with autopilot engaged before flap retraction. The first MCAS activation was not immediately after flaps up, but only after the autopilot disengaged a few seconds later. A subtle difference perhaps?
