Dithering constant error in Unity

Hello,

I am using the Post-processing stack V2 I believe (Unity version 2018.3.12f1), and when I turn on/select the "Dithering" option in the post-process settings it gives me this error in the editor (and all the time during runtime as well):

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object
2. UnityEngine.PostProcessing.DitheringComponent.Prepare (UnityEngine.Material uberMaterial) (at Assets/PostProcessing/Runtime/Components/DitheringComponent.cs:63)
3. UnityEngine.PostProcessing.PostProcessingBehaviour.TryPrepareUberImageEffect[T] (UnityEngine.PostProcessing.PostProcessingComponentRenderTexture`1[T] component, UnityEngine.Material material) (at Assets/PostProcessing/Runtime/PostProcessingBehaviour.cs:457)
4. UnityEngine.PostProcessing.PostProcessingBehaviour.OnRenderImage (UnityEngine.RenderTexture source, UnityEngine.RenderTexture destination) (at Assets/PostProcessing/Runtime/PostProcessingBehaviour.cs:255)
5.  

It also causes my particles and skysphere to disappear in my game, although that could be simply because of the error, but I'm not sure. It happens every frame I believe in runtime, and spams in the editor when I hover over different windows.

I've tried "Dithering" in both Forward and Deferred rending, but it throws the error in both modes. Does anyone know what might be causing this?

 

been a year since then and this is still a issue, cmon someone answer already
