Android Scene compose crash

Version 2.2.1

Log

Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x2a8 in tid 14174 (alth.example.com), pid 14174 (alth.example.com)

A crash happened when hiding the Scene compostable

var visible by remember { mutableStateOf(true) }
if (visible) {
    Scene(...)
}
Button(
    onClick = {
        // Crash happened here
        visible = false
    }
) {
    Text("hide")
}

It won't crash if we navigate back, only on hiding compostables.

Update

A workaround to fix this issue is to remove all models before calling the destroy() function.

In Scene:

onRelease = { sceneView ->
    sceneView.childNodes = emptyList()
    sceneView.destroy()
}

Where exactly are you setting the onRelease? As far as I can tell neither the ARScene nor the Scene have such a attribute?

This is inside the Scene file in the library.
If you want to do it yourself you need to create a custom composable and use AndroidView to create a SceneView.

The onRelease parameter is inside AndroidView.

The workaround did not resolve it for me. In fact, I can recreate this crash with an empty scene with no nodes.
