LocationManager did stop

Why locationManager did disconnect in this circumstance?

Always after START -> STOP -> START service.

locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = 5; // meters
locationManager.allowsBackgroundLocationUpdates = YES;
locationManager.pausesLocationUpdatesAutomatically = NO;

if (@available(iOS 14.0, *)) {
    if (locationManager.authorizationStatus == kCLAuthorizationStatusAuthorizedWhenInUse){
      [locationManager startUpdatingLocation];
    } else {
      shouldStart = false;
      [locationManager requestWhenInUseAuthorization];
    }
  } else {
    // Fallback on earlier versions
  }
