Can't get NavigationRouter via protocol

[PortgasDTee]

@RouterObject var authRouter: NavigationRouter<AuthCoordinatorType>?
AuthCoordinator have been init and router stored but when I use authRouter, it is nil

protocol AuthCoordinatorType: AnyObject {}

final class AuthCoordinator: AuthCoordinatorType, NavigationCoordinatable {
lazy var routerStorable: AuthCoordinatorType = self
...
}

I checked on func func retrieve<T: Routable>() -> T? in class RouterStore
Stored router have type NavigationRouter<AuthCoordinator> can't cast to NavigationRouter<AuthCoordinatorType>
