How can I solve the problem of createCameraVideoTrack timeout?

Question

I am using Angular and Agora to make a ChatApp.

this method is working fine the token the uid the channel ... ` async joinRoomInit() {

  // create a client
  this.client = AgoraRTC.createClient({mode:'rtc', codec:'vp8'});
  // Join a specific room
  await this.client.join(environment.agoraAPI, this.roomid, environment.agoraToken, this.uid);
  this.joinStream();    }`

` async joinStream() {

  const AudioTrack = await AgoraRTC.createMicrophoneAudioTrack();
  console.warn('Audio created');
  const VideoTrack = await AgoraRTC.createCameraVideoTrack();
  console.warn('video track is created');
  // Publish the local audio and video tracks to the RTC channel.

  await client.publish([AudioTrack, VideoTrack]);

  let player = '<div class="video-call" id='user-id-this.uid'"></div>';
  document.querySelector('.left-side')?.insertAdjacentHTML('afterbegin', player);
  VideoTrack.play(user-id-{this.uid);}

`

The Audio track is created succesfully because it returns this Agora-SDK [INFO]: create microphone audio track success, trackId: track-mic-ea57500d , but AgoraRTC.createCameraVideoTrack is not working it gives me as result in the console : Agora-SDK [DEBUG]: createCameraVideoTrack timeout the same problem appears when using another method AgoraRTC.createMicrophoneAndCameraTracks the Mic and Video are both allowed in chrome. I don't really know what or where does the problem coming from. Any Help would be appreciated.
