Bug Could not load file Unity.SourceGenerators.dll

I am trying to learn following the tutorials and documents, but I have been getting the following warnings and somewhat lacking on data types and methods from the tutorials, such as the WorldTransform, localTransform in Unity.Transforms.


Warning CS8032 An instance of analyzer Unity.MonoScriptGenerator.MonoScriptInfoGenerator cannot be created from E:\Unity2\2022.2.0b16\Editor\Data\Tools\Unity.SourceGenerators\Unity.SourceGenerators.dll: Could not load file or assembly 'netstandard, Version=2.1.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. . Assembly-CSharp E:\Unity2\2022.2.0b16\Editor\Data\Tools\Unity.SourceGenerators\Unity.SourceGenerators.dll 1 Active


I confirmed the path has this Unity.SourceGenerators.dll file and the latest Rider also gives warnings with it.

I have tried with lower versions of .NET and Trying to change the API compatibility Level option to .NET Framework in Edit > Project Settings > Player > Other Settings has no effect

Same error appeared to me today.
Was working fine yesterday evening.

I didn't touch anything, loaded Unity today, created a new script and the warning is present
