Cast to game instance failing (from animation blueprint)

[GRooVy_GRoVer]

hello everyone,

I have run into a problem.
I try to cast to my game instance from a animation blueprint, but it keeps falling:

its weird because a already cast a lot to my game instance, and works fine everytime, but in a animation blueprint it keeps falling.
I already have set this game instance as defaut:

what can I do about this?
