Hi, I don't have an Alexandrine, but the same exact thing happened to me when we clipped our sun conure's wings. I think it is a combination of trust being "violated" and your bird being completely out of its comfort zone not being able to fly. It's a scary thing for them, they don't understand, they just know you are probably to blame. Maui didn't want anything to do with us and bit us a lot during the transition.
It took a solid 2 weeks for Maui to get comfortable again, I would give it time and continue trying to work with him, but don't push him too much, be gentle and available. We opened her door and sat by her cage a lot
