Getting stuck in first frame of renderLoop.

First I get this ar_world_tracking_provider_query_device_anchor_at_timestamp <0x302b9c0a0>: The device_anchor can only be queried when the world tracking provider is running.

// Pace frames by waiting for the optimal prediction time.
        try await LayerRenderer.Clock().sleep(until: timing.optimalInputTime, tolerance: nil)
        
        // Start submitting the updated frame.
        frameLayer.startSubmission() <-
