There is a fear period around 10 months that could explain the sudden fear/aggression. Keep up the socialization and he will soon work through it. There is a last push of the rear molars around 10 months also. I have experienced 10-11 month old pups being pretty destructive during this period because their jaws are strong and teeth are big. I would give him lots to chew around this time and you might have to crate him until this has past.
