That assumes that an AoA failure occurs before flap retraction, a latent fault could show itself at any point although takeoff (ET) is the most likely.
Bird strike also a possibility for a significant window after takeoff.
Intermittent wiring or other faults can also happen at any point, some possibility this was a factor in Lion Air, mysterious 20 degree offset after replacing suspect AoA sensor but no proof at this point.
