Error in CyanEmuPlayerController.cs when loading CyanEmu

[morganite-proto]

When loading CyanEmu from the Unity Package, the following error appears in the console. This prevents CyanEmu from loading in properly.

Assets\CyanEmu\Scripts\CyanEmuPlayerController.cs(13,29): error CS0234: The type or namespace name 'PostProcessing' does not exist in the namespace 'UnityEngine.Rendering' (are you missing an assembly reference?)

This is with VRC SDK3 2021.03.22

My first impression is that this could be a bug relating to files in your project. Do you happen to have any classes named "PostProcessing" that isn't the standard post processing package? This can cause compile errors.
I ask this as it is similar to the bug that happens when someone has NoodleBowl imported. This package defines a script called Button.cs, which breaks all references to Unity's UI.Button class.
