It seems like you code against a concrete implementation and not the interface EventEspresso\core\services\collections\CollectionInterface as the method loadResolvers() does only exist in the following implementations of said interface: EventEspresso\core\services\graphql\ResolverCollection.

        add_action('graphql_register_types', [$this, 'registerResolvers']);
    }

        // We're taking care of calling register_graphql_field() from here,
        // which centralizes where everything happens, allowing for more control
        // and making the resolver classes easier to unit test because
        // they are decoupled from the third party api
