4 Errors when building game with XR Toolkit using openVR

Hello,

I'm having an issue when building a small project with just a XR Rig. There is 4 Errors that Unity throws. I have read through them but I don't understand the issue as I'm new to the XR Toolkit. I'm really just working on some ideas for weapon handeling in VR. Thank you for any help.

Hey, I've got this same issue on 2019.4.4f1. Based on the message, it seems likely to be an error with the Post Processing Stack. Did you ever have any luck fixing it?

EDIT: For anyone else encountering this, it seems for a reason unknown to me, my Windows SDK was no longer being picked up by IL2CPP. Uninstalling and reinstalling the SDK via Visual Studio's Installer solved it.
