Steamvr doesnt work with posteffects V1 or V2 using Unity 2019

I have tried with single pass and single pass instanced and none work with Unity 2019.2 using posteffects, it works fine with 2018.3
With single pass instanced renders well just the right eye and the left appears as grey color, but all the assets use the Unity Standard asset so they should work with any shader changes
With single pass everything appears black, nothing is rendered
I tried to reenable VR in project settings but doesnt solve anything

 

I see creating a new project posteffects works in single pass with posteffects but not in my project which shows a distorted image as can be seen in the pic. In my scene i see everything black but when create a new scene in my project i dont get everything black but the image stretched and with single pass instanced i get the left eye grey and the right with normal color without any distortion, any ideas?
