CrowdNavigation Problem

Hello everyone,
I am trying to implement crowd navigation on my project, but the function OnCrowdUpdate isn’t be called, this way, I haven’t the event E_CROWD_AGENT_REPOSITION handler.

I don’t know why Im getting troubles about it, in-game I can see the NavigationMesh and the CrowdAgent, but when I call SetCrowdTarget, Im getting a code failure on library function:

Debbugging, I see this ref is zero retrieved from queryPolygons function:

Someone knows what is happening?
Thanks.
