AVPlayerView crash in Swift

Question

In my macOS App I have a window with a AVPlayerView. When run from Xcode the window opens and the video plays. However, when I export (Archive>Copy App) the app and open it the window with AVPlayerView crashes.

I suspect the issue is that the app is unable to access the video file when the app is exported.

import Cocoa
import AVKit

class IntroVC: NSViewController{
    override func viewDidLoad() {
        super.viewDidLoad()
        avViewConfig()
    }
    @IBOutlet weak var avView: AVPlayerView!
    
    
    func avViewConfig(){
        
        if let filePath = Bundle.main.path(forResource: "one", ofType: ".mp4") {
            let filePathURL = NSURL.fileURL(withPath: filePath)
            
            let player = AVPlayer(url: filePathURL)
            
            avView.player = player
            avView.player?.play()
        }
    }
}

I added the video file by dragging it directly into the project folder.

Still don't know what the issue was but removing the AVPlayerView from the storyboard and programatically adding one seems to have fixed the issue.

class IntroVC: NSViewController{
    override func viewDidLoad() {
        super.viewDidLoad()
        avViewConfig()
        avPlayerView.frame = self.view.frame
        view.addSubview(avPlayerView)
    }
    
    var avPlayerView = AVPlayerView()
    
    func avViewConfig(){
        
        if let filePath = Bundle.main.path(forResource: "one", ofType: ".mp4") {
            let filePathURL = NSURL.fileURL(withPath: filePath)

            let player = AVPlayer(url: filePathURL)

            avPlayerView.player = player
            avPlayerView.player?.play()
        }
    }
}
