Can't load bundle with unity built-in shaders

Hi! I met strange issue when added to addressable bundle an asset which use a built-in shader - for some reason, on loading dependencies it tries to load

unitybuiltinshaders.bundle

as JSON though it is binary. (doesn't depend on platform, happening in editor)

Preload bundle with the asset:

Code (csharp):

1. Addressables.DownloadDependenciesAsync(new List<string> {...}, Addressables.MergeMode.Union);

Exceptions:

Code (csharp):

1. ArgumentException: Cannot deserialize JSON to new instances of type 'IAssetBundleResource.'
2. UnityEngine.JsonUtility.FromJson (System.String json, System.Type type) (at <0b59f3b614a04547a8bf657de1e23f2c>:0)
3. UnityEngine.ResourceManagement.ResourceProviders.JsonAssetProvider.Convert (System.Type type, System.String text) (at Library/PackageCache/com.unity.addressables@1.19.19/Runtime/ResourceManager/ResourceProviders/JSONAssetProvider.cs:20)
4. UnityEngine.ResourceManagement.ResourceProviders.TextDataProvider+InternalOp.ConvertText (System.String text) (at Library/PackageCache/com.unity.addressables@1.19.19/Runtime/ResourceManager/ResourceProviders/TextDataProvider.cs:143)
5. UnityEngine.AsyncOperation:InvokeCompletionEvent()
6.  
7. OperationException : Unknown error in AsyncOperation : Resource<IAssetBundleResource>(StandaloneWindows64\c7a560711722c2a503b6e84889a4a5e7_unitybuiltinshaders.bundle)

There is specialty that assets and code are in separate projects, code project uses existing bundles that were built from the asset project.
I tried to reproduce it in a new project (single), but no the issue.

Unity 2020.3.11f1, addressable 1.19.19.

Does anyone have idea what it could be the reason?

 

Thanks!
