Not much doubt a stall occurred, either from too little speed or excessive attitude and over-correction.
There appears to be too little time for a low speed stall over-corrected by diving for speed to then over-speed and get airframe failure.
In the Qantas Airbus incident, the pilots decided that the aircraft had stalled and then over-speeded simultaneously, which commanded a negative G pushover followed by a pitch up, suddenly climbing 300 feet and then abruptly pitched nose down into a steep dive.
The maneuver exceeded the design certification of the airframe. Luckily the pilots regained control, many passengers injured. That's why I theorize that over-speeding may have been the original problem causing a loss of control cascade.

The ‘alternate law’ rudder travel limiter fault suggests that the problems started in the rear.
Where is the antenna for the TCAS located? If you know.
02:10Z: FBW alternate law Rudder Travel Limiter Fault
Is very troubling. If the the entire air data system and gyros were lost, as the fault messages indicate and that caused the rudders full travel.....
Tumbling, big trouble. Icing, turbulence, whatever, does not explain the loss of the internal gyros, maybe lighning, maybe.
If it went nose up due to over-speeding, and was hit by a 100mph updraft, it could have ripped the tail and/or wings off.
This is the key error message. Once this happened, they were doomed because the flight-control system is then not operational, and the pilot has no mechanical backup and no way to control the A/C. The flight control surfaces go nuts.......
Who knows what occurred here, but I think a stall is unlikely. If the computer 'sees' low speed from the dead pitot heads, it would probably lower the nose and a dive would occur, without a stall. After passing Vne, it would break up.
