Attaching weapon to character not working

Thr Problem its still unsolved and i really know whats the problem is it a bug or something because my weapon doesnt seemed want to attach to the socket anymore

Im asking this once again cause the old one its still not solved

so whats wrong and i get around this problem by attaching it manually like this to the parent via the viewport but i still kinda hope for more subtle approach using the blueprint

The Controller

The Actor

Please help me if someone experiencing this sort of thing and know how to solved it

I personaly spawn the character and the weapon then I attach the weapon using Attach to Actor node (or something like that)
