Black screen after updating to Unity 2019.1.61f

I had updated my project to Unity 2019.1.61f i cant see anything, just a black screen, its a VR project for HTC Vive with Steamvr and now it doesnt work at all and i receive lot of errors

"Could not load symbol ovrp_EndEye2"
"Could not load symbol ovrp_SetDepthProjInfo"
I get a lot of errors which start with "Maximum number (256) of shader global keywords exceeded"
"Shader error in 'Hidden/VelocityShaderCTAASPS': "missing keyword CAMERA_..." at line 96 (on d3d11)"

 

Already found the error, can be seen here
https://github.com/Unity-Technologies/PostProcessing/issues/795
VR is broken in Unity 2019
Hours to update to 2019 and now hours i will need to downgrade to Unity 2018

 

Updated to Unity 2019.2.01f and the error remains, this should be a priority
