Ios swift – iOS App crashing due to Camera permission

I have a view controller where I’m trying to open a camera to scan a QR code. Every time I open the VC it crashes my app with an error message:

This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app’s Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data.

I have double-checked my info.plist and in Target as well. I have permitted the camera usage already, but still facing the same error every time. What is the missing dot? Here is my VC code:

import UIKit


import AVFoundation

class Scanner__VC: UIViewController, AVCaptureMetadataOutputObjectsDelegate {
var captureSession: AVCaptureSession!
var previewLayer: AVCaptureVideoPreviewLayer!




override func viewDidLoad() {
    super.viewDidLoad()

    
    view.backgroundColor = UIColor.black
            captureSession = AVCaptureSession()

            guard let videoCaptureDevice = AVCaptureDevice.default(for: .video) else { return }
            let videoInput: AVCaptureDeviceInput

    do {
        videoInput = try AVCaptureDeviceInput(device: videoCaptureDevice)
        
    } catch {
                return
            }

    if (captureSession.canAddInput(videoInput)) {
        captureSession.addInput(videoInput)
        
    } else {
        failed()
        return
        
    }

            let metadataOutput = AVCaptureMetadataOutput()

    if (captureSession.canAddOutput(metadataOutput)) {
        captureSession.addOutput(metadataOutput)
        
        metadataOutput.setMetadataObjectsDelegate(self, queue: DispatchQueue.main)
        metadataOutput.metadataObjectTypes = [.qr]
        
    } else {
        failed()
        return
        
    }

    previewLayer = AVCaptureVideoPreviewLayer(session: captureSession)
    previewLayer.frame = view.layer.bounds
    previewLayer.videoGravity = .resizeAspectFill
    view.layer.addSublayer(previewLayer)

    captureSession.startRunning()
    
}


func failed() {
    let ac = UIAlertController(title: "Scanning not supported", message: "Your device does not support scanning a code from an item. Please use a device with a camera.", preferredStyle: .alert)
    ac.addAction(UIAlertAction(title: "OK", style: .default))
    present(ac, animated: true)
    captureSession = nil
    
}

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    
    if (captureSession?.isRunning == false) {
        captureSession.startRunning()
    }

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    
    if (captureSession?.isRunning == true) {
        captureSession.stopRunning()
    }
    
}

func metadataOutput(_ output: AVCaptureMetadataOutput, didOutput metadataObjects: [AVMetadataObject], from connection: AVCaptureConnection) {
    captureSession.stopRunning()
    
    if let metadataObject = metadataObjects.first {
        guard let readableObject = metadataObject as? AVMetadataMachineReadableCodeObject else { return }
        guard let stringValue = readableObject.stringValue else { return }
