Assertion failed after calling session.startDetecting() - Xcode 15.0 beta1 (15A5160n)

I followed the instruction in this session and tried to write a demo with Object Capture API. But there's a MTLDebugRenderCommandEncoder assertion fails every time I call session.startDetecting(), just after the bounding box shows up.

The error shows:

-[MTLDebugRenderCommandEncoder validateCommonDrawErrors:]:5780: failed assertion `Draw Errors Validation
Fragment Function(fsRealityPbr): the offset into the buffer clippingConstants that is bound at buffer index 8 must be a multiple of 256 but was set to 128.

and my code is pretty simple:

var body: some View {
    ZStack {
        ObjectCaptureView(session: session)
        if case .initializing = session.state {
            Button {
                session.start(imagesDirectory: getDocumentsDir().appendingPathComponent("Images/"), configuration: configuration) // 💥
            } label: {
                Text("Prepare")
            }
        } else if case .ready = session.state {
            Button {
                session.startDetecting()
            } label: {
                Text("Continue")
            }
        } else if case .detecting = session.state {
            Button {
                session.startCapturing()
            } label: {
                Text("Start Capture")
            }
        }
    }
}

I'm wondering if anyone else is facing the same problem or if there's an error on my side?
