The part that has came off is just a press fit into the part stuck in the wheel.
The slip ring just covers the join in both these parts.
Line up the part that has came off with the part still in the wheel and hammer it in place until it feels secure.
Then try to turn the bolt out carefully.
Maybe undo the locking bolts on the other wheels first in case you break the locking wheel socket.
