Problem with building the asset bundle with scene

Unity Engine

After updating my project to 2022.2.1f1 I found a very problematic bug that won’t let me to build asset bundles that containing scene. I got a message after 50 seconds:

Object reference not set to an instance of an object```

The problem occurs in my code here:

```csharp
private ReturnCode BuildBundles(IBundleBuildContent buildContent, IBundleBuildParameters buildParameters)
{
   var taskList = Bundles.Tasks.Build.CalculateAndBuildBundles(); //<----------- here
   var code = ContentPipeline.BuildAssetBundles(buildParameters, buildContent, out var results, taskList);

   return returnCode;
}

public static IList<IBuildTask> CalculateAndBuildBundles()
{
   var buildTasks = CalculateCommonBundles(); //<----------- here

   // Dependency
   buildTasks.Add(new StripUnusedSpriteSources());
   buildTasks.Add(new PostDependencyCallback());

   // Packing
   buildTasks.Add(new GenerateBundlePacking());
   buildTasks.Add(new GenerateBundleCommands());
   buildTasks.Add(new GenerateSubAssetPathMaps());
   buildTasks.Add(new GenerateBundleMaps());
   buildTasks.Add(new PostPackingCallback());

   // Writing
   buildTasks.Add(new WriteSerializedFiles());
   buildTasks.Add(new ArchiveAndCompressBundles());

   buildTasks.Add(new CalculateDiffSignatures());
   buildTasks.Add(new WriteResimoManifest());
   buildTasks.Add(new PostWritingCallback());
   return buildTasks;
}

public static IList<IBuildTask> CalculateCommonBundles()
{
   var buildTasks = new List<IBuildTask>();

   // Setup
   buildTasks.Add(new SwitchToBuildPlatform());
   buildTasks.Add(new RebuildSpriteAtlasCache());

   buildTasks.Add(new BuildPlayerScripts());
   buildTasks.Add(new PostScriptsCallback());

   //Remove duplicated textures
   buildTasks.Add(new CalculateScenesDuplicatedDependencies());
   buildTasks.Add(new StripTextures());
   buildTasks.Add(new RefreshAssetDatabase());

   buildTasks.Add(new CalculateSceneDependencyData()); //<----------- here
   buildTasks.Add(new CalculateAssetDependencyData());

   return buildTasks;
}

When I test remove calling the CalculateSceneDependencyData(), I got the exception in ContentPipeline.BuildAssetBundles:

The given key '94658ac7db67db047947acd7a55d4bac' was not present in the dictionary.```

I tried another versions of unity like **2022.2.3f1**, **2022.2.2f1**, **2022.2.0b16**, **2022.2.0b10** and even **2023.1.0a18** but the problem also exists. The last working version is **2022.1.24f1**.

I removed any other asset bundles and left only this one with scene. I made sure that no dependencies are in several bundles. I also tried to build empty scene. Nothing helped. Only if I back to previous version (2022.1.24f1) the problem will disappear...

Has anyone encountered this problem?
