Crash on Android (FEngine::loop)

[deviserandroid]

Bug Description I am using the AR Core and ARScene to detect the surface and add Renderable Model on the surface. Most of the time, app crashes with logs added below.

Steps To Reproduce Steps to reproduce the behavior:

1. Open the Ar Activity to detect the surfaces.
2. When the surface is detected render a model on the surface.
3. Things works just fine until user exists the ArActivity.
4. Exit from the Ar Activity, and reopen the ArActivity to detect the surfaces. App will crash randomly while detecting the surface.

Additional context Code to load surface detection model `val bitmap = BitmapFactory.decodeResource(resources, R.drawable.surface)

    Texture.builder()
        .setSource(bitmap)
        .build().thenAccept { texture ->
            MaterialFactory.makeTransparentWithTexture(this, texture)
                .thenAccept { material: Material? ->
                    bitmap.recycle()

                    focusSquareModel = ShapeFactory.makeCylinder(0.1f, 0f, Vector3.zero(), material)
                    focusSquareModel!!.isShadowCaster = false
                    focusSquareModel!!.isShadowReceiver = false
                }
        }`

Code to load 3D Arrow Model `ModelRenderable.builder() .setIsFilamentGltf(true) .setAsyncLoadEnabled(true) .setSource(this, R.raw.target_model) .build() .thenAccept { modelRenderable -> modelRenderable?.isShadowCaster = false modelRenderable?.isShadowReceiver = false model = modelRenderable

        }
        .exceptionally { _ ->
            null
        }`

Things that I have tried so far:

1. Detach the Anchors, release the renderable model, close the ARFragment's session when the ARActivity is destroyed.
2. Comment out the code to observe the Scene's addOnUpdateListener that detects the surface and add Renderable model on the surface. Also comment the code to load the Model.
