I have previous accident reports involving the A320 to use as a guide. Very similar circumstances have lead to other A320 crashes. You may want to enlighten yourself of this information and the issues that exist with the flight control system in the A320. This information is readily available through the FAA’s accident investigation site.
I don’t doubt your information that there are problems with A320’s flight control system. The point is that if the audio recording for this particular flight reveals that the pilot was desperately trying to regain access to the cockpit, but was manually locked out by the copilot, who was awake and breathing normally while everyone else was screaming in terror, it seems exceedingly unlikely that this situation in the cockpit was unrelated to the crash and the actual cause was some mechanical problem that went unnoticed. Do you not see how monumentally illogical that is?
