Any tips on how to get this guy to be nicer?

He used to be so so sweet and now he’s rude as hell and MOODY. He’s about 14 weeks old. A couple times he’s jumped at me for no reason, just filling up the feed. Just a bit ago I was out there giving some treats (chopped up strawberries that I won’t finish) and he was fine taking treats and then all of a sudden he was trying to jump at my face. He’s very wishy washy cause one moment he’s fine and the next he’s trying to claw my eyes out. When I hold him hes fine, loves pets while he’s in my lap, goes straight to sleep and just chills. But it seems like his attempts to attack me are just out of nowhere.

Silly picture of me and the menace in question from a week ago after he tried to get me and I yoinked him and put him in snuggle jail and another one of just him cause he’s a pretty bird. His name is Nutmeg by the way lol.
