There fork crown has a "pocket" moulded into the back of the upper surface. (pic 1). Have a look to see if this is damaged - if it is, consult your dealer.
There's a metal pin that is bonded into the frame. (pic 2) This may have come out, which may be as innocent as it becoming un-bonded or dropping out. Or this may have broken out and the frame is damaged. If the frame is damaged, consult your dealer.
Hope this helps. To drop your fork, undo the top cap bolt; un-tighten your stem bolts around the steerer tube (rear end of stem); release your front brake cable; and drop the fork out. When the fork comes free, your stem will flop around and your bars probably dive towards the floor, so support those with one hand.
