App crash on setModel method of ModelNote class

[DerkachYuriy]

Hello
I don't really understand why my app crashes on setModel method:

    private fun addObjectToSceneProcessHit(hit: HitResult, sceneView: ArSceneView?, objectRenderable: Model): ArModelNode? {
        Log.i(TAG, "Process hit")
        val frame = sceneView?.currentFrame
        if (frame?.camera?.trackingState == TrackingState.TRACKING) {
            val anchor = hit.createAnchor()
            val anchorNode = ArModelNode(placementMode = PlacementMode.PLANE_HORIZONTAL)
            anchorNode.isSmoothPoseEnable = false
            anchorNode.anchor = anchor
            anchorNode.parent = sceneView
            anchorNode.setModel(objectRenderable, autoAnimate = false)
            return anchorNode
        }
        return null
    }

App crashes in this row:
anchorNode.setModel(objectRenderable, autoAnimate = false)
when this method tries to get model.entities inside ModelNote class

Hi,
Can you provide the crash logs?

This is all that I have, in this case

The issue might come from your model.
Try to use one coming from the samples and see if you have an issue with it.

I successfully run your "model-viewer" sample on my android device. But I found an issue with it.
I wrote this code in Activity.kt:

        supportFragmentManager.beginTransaction().addToBackStack("").replace(R.id.containerFragment, SomeFragment()).commit()
        supportFragmentManager.beginTransaction().addToBackStack("").replace(R.id.containerFragment, MainFragment()).commit()

It's the only change that I've made, just to create another simple fragment with the text, to test how well MainFragment() will finish it's work by onBackPressed.

And test wasn't successful - app got crash:

18:44:25.943  A  Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x6d0 in tid 4843 (ple.modelviewer), pid 4843 (ple.modelviewer)

Help me please with that. Because my app that uses your library has the same architecture - a lot of fragments in a single activity. And the fragment with your io.github.sceneview.SceneView is one of them.
