In a large bowl, mix together the cream cheese, mayonnaise, sour cream and heavy cream until smooth. Stir in the Asiago, lemon juice, hot sauce, salt, pepper, seafood seasoning and 1/2 cup of the Cheddar until well combined. Fold in the crab meat. Transfer to a 1-quart baking dish and sprinkle with the remaining Cheddar.
Bake until browned and bubbling, 30 to 35 minutes. Serve with crackers, bread or tortilla chips!
