他の投稿の助けを借りて解決策を見つけました。タイミングの問題であることが判明しました。ロケーションマネージャーをリセットする別のメソッドを作成し、それを遅らせて呼び出しました。これですべてが修正されました。これがあなたにも役立つことを願っています。

- (void)stopLocationManager
{
    if (locationManager)
    {
        [locationManager stopUpdatingLocation];
        [self performSelector:@selector(discardLocationManager) withObject:nil afterDelay:0.1];
    }
}

- (void) discardLocationManager
{
    locationManager.delegate = nil;
    locationManager = nil;

    if (self.isRestart == YES)
    {
        [self performSelector:@selector(startupLocationManager) withObject:nil afterDelay:0.1];
    }
}
