Preheat oven to 375°F.
Slice the French bread in half lengthwise. Lightly toast in the oven for 5–7 minutes until slightly crisp.
In a bowl, mix together cream cheese, chopped crab, green onions, garlic powder, onion powder, soy sauce, sugar, and Worcestershire sauce until smooth and well combined.
Remove the bread from the oven. Gently hollow out a small amount of the center to make room for the filling. Spread the crab mixture.
Sprinkle mozzarella generously on top.
Return to the oven and bake for 10-12 minutes or until the cheese is melted and bubbly.
Broil for 1–2 minutes until the top is golden and slightly crispy (watch closely!).
Drizzle with sweet chili sauce, slice, and serve warm.
