Mix imitation crab, cream cheese, green onions, ginger, garlic powder, and onion powder in a medium bowl until well blended.
Place beaten egg in a small bowl; set aside. For each wonton, place a wonton wrapper on a clean work surface. Place 2 teaspoons of crab filling in the center of the wrapper. Brush edges of the wonton with egg. Bring up 2 opposite corners of the wonton wrapper, pressing together to seat at points and along edges. Repeat with other 2 corners, pressing to seal completely.
Preheat air fryer to 350°F for 3 minutes. Working in batches, place crab Rangoon in a single layer in the air fryer basket; do not overcrowd. Spray wontons lightly with no-stick cooking spray. Air fry for 5 minutes or until golden brown and crispy and filling is heated through. Repeat with remaining wontons. Serve with Sweet Red Chili Sauce for dipping.
