we have the same issue

[Daphne-CoffeeIT]

I might have run into the same issue. For me the app crashes after closing the ModalBottomSheet or after navigating onwards while using Scene inside a Card component. Annoyingly no stack trace showed up in the logs. What fixed my issue is adding the following:

var sceneView by remember { mutableStateOf<SceneView?>(null) }

DisposableEffect(lifecycleOwner) {
    onDispose {
        sceneView?.let { view ->
            view.childNodes = emptyList()
        }
    }
}

Inside the Scene component I assign the sceneView variable as follows:

onViewCreated = {
    sceneView = this
}

I hope this works for you too.

In my case when I opened the bottom sheet it gets crashed
