In a large bowl, mix together the egg, mayonnaise, mustard, Worcestershire sauce, seasoning, salt, pepper, celery, parsley, bell pepper, and crab meat. Carefully fold in the breadcrumbs last.
Shape the mixture into eight crab cakes and place them on a parchment-lined plate. Freeze for 5 minutes.
Preheat your air fryer to 400°F.
Lightly grease the air fryer basket. Place four crab cakes in the basket and cook for 7-8 minutes, flipping them halfway through the cooking time. Repeat with the remaining crab cakes until all are cooked.
