SKScene as SCNPlane material diffuse content frame drop or crash with scene prepare

Hello, I'm trying to place and play a local video on a detected ARKit image.

Here's a code example which has either the frame drop (camera view freezes for ~ half a second) or the crash:

Code Block swiftguard let fileUrlString = Bundle.main.path(forResource: "videoname", ofType: "mp4") else { return }
        let videoItem = AVPlayerItem(url: URL(fileURLWithPath: fileUrlString))
        let videoPlayer = AVPlayer(playerItem: videoItem)
        let videoNode = SKVideoNode(avPlayer: videoPlayer)
        let videoScene = SKScene(size: CGSize(width: 1080, height: 1080))
        videoScene.addChild(videoNode)
        let videoPlane = SCNPlane(width: 0.1, height: 0.1)
        /* CAUSE OF FRAME DROP ON FIRST ADDCHILDNODE */
        videoPlane.firstMaterial?.diffuse.contents = videoScene
        let videoPlaneNode = SCNNode(geometry: self.videoPlane)
        videoPlaneNode.eulerAngles.x = -Float.pi * 0.5
        /* CAUSE OF CRASH IF UNCOMMENTED WITH 				 	videoScene AS MATERIAL DIFFUSE CONTENT */
        self.sceneView.prepare([videoPlaneNode], completionHandler: { (success) in
			self.sceneView.scene.rootNode.addChildNode(videoPlaneNode)
        })
        			self.sceneView.scene.rootNode.addChildNode(videoPlaneNode)

Code Block swift
guard let fileUrlString = Bundle.main.path(forResource: "videoname", ofType: "mp4") else { return }

let videoItem = AVPlayerItem(url: URL(fileURLWithPath: fileUrlString))

let videoPlayer = AVPlayer(playerItem: videoItem)

let videoNode = SKVideoNode(avPlayer: videoPlayer)

let videoScene = SKScene(size: CGSize(width: 1080, height: 1080))

videoScene.addChild(videoNode)

let videoPlane = SCNPlane(width: 0.1, height: 0.1)

/* CAUSE OF FRAME DROP ON FIRST ADDCHILDNODE */

videoPlane.firstMaterial?.diffuse.contents = videoScene

let videoPlaneNode = SCNNode(geometry: self.videoPlane)

videoPlaneNode.eulerAngles.x = -Float.pi * 0.5

/* CAUSE OF CRASH IF UNCOMMENTED WITH videoScene AS MATERIAL DIFFUSE CONTENT */

self.sceneView.prepare([videoPlaneNode], completionHandler: { (success) in
self.sceneView.scene.rootNode.addChildNode(videoPlaneNode)
})

self.sceneView.scene.rootNode.addChildNode(videoPlaneNode)

I was trying to use the prepare method to avoid frame drops (not sure I'm using it correctly) but it crashes with this message:

Code Block swiftSceneKit`C3DSceneGetAnimationManager:
->	0x1ac5c36b4 <+0>: ldr		x0, [x0, #0x48]
		0x1ac5c36b8 <+4>: ret

-> 0x1ac5c36b4 <+0>: ldr x0, [x0, #0x48]

How can I solve this?

Thanks
