Scene is not Loading

There are 9 scenes in total. All are Added in "Build Settings". 7 scenes out of 9 are loading, but when I try to load other 2 scenes it kept saying:

Scene 'SceneName' couldn't be loaded because it has not been added to the build settings or the AssetBundle has not been loaded. To add a scene to the build settings use the menu File->Build Settings... UnityEngine.SceneManagement.SceneManager:LoadSceneAsync(String, LoadSceneMode) MoreMountains.CorgiEngine.c__Iterator0:MoveNext() (at Assets/CorgiEngine/Common/Scripts/Managers/LoadingSceneManager.cs:88) UnityEngine.MonoBehaviour:StartCoroutine(IEnumerator) MoreMountains.CorgiEngine.LoadingSceneManager:Start() (at Assets/CorgiEngine/Common/Scripts/Managers/LoadingSceneManager.cs:67)

Here is my "Scene In Build" Image

I have already added the scene in the scene manager but it keeps showing this error. I have tried so much. Please help me to sort out the problem. Here is my "LoadingSceneManager" script:

using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using System.Collections.Generic;
using MoreMountains.Tools;
using UnityEngine.SceneManagement;

namespace MoreMountains.CorgiEngine
{   
public class LoadingSceneManager : MonoBehaviour

    /// The name of the scene to load while the actual target scene is 
    loading (usually a loading screen)
    public static string LoadingScreenSceneName="LoadingScreen";

    [Header("GameObjects")]
    /// the text object where you want the loading message to be displayed
    public Text LoadingText;
    /// the canvas group containing the progress bar
    public CanvasGroup LoadingProgressBar;
    /// the canvas group containing the animation
    public CanvasGroup LoadingAnimation;
    /// the canvas group containing the animation to play when loading is complete
    public CanvasGroup LoadingCompleteAnimation;

For some reason, I had all the scenes added in Build Settings properly, but it was still throwing an error when running the game in the editor (no problem when built for android).

I just removed all scenes from the Build Settings and added them back again. No problem at all after that.

I know this question is old but my answer might be still valuable to some people having this problem. The scenes you add to your build should avoid more exotic characters like german umlauts "äöÜß" or simmilar. And it'll be better if you avoid whitespace characters as well - as they might contain some other sign then you suspect and therefore cause trouble. Especially when you did a copy&paste to name them. So better stick to plain ASCII letters and replace all blanks with hyphen or underscore.

Please check your function "LoadScene".

I'm not sure what exact problem is but from your logs the problem is in "LoadScene" function.

It's look like You try to load scene with name: 'SceneName'.

  1. Check if You have proper values on functions parameters.
  2. Try to load problematic scenes using indexes instead of names.

or you can use by their index values its much easier approach rather then using string

SceneManager.LoadScene(0);

and then add all those scene by opening build setting window

Have you added your scene which you try to load into the build settings "Scenes In Build" Section? This is required to switch to any scene inside your project using the scenemanager.
