Kernel 'KMain' not found.

When i build and start the game all the post effects seem to be off. There is no issues in the editor and editor play mode.
I started from a new project (3D with extras) then changed the rendering (project settings) to deferred and added screenspace reflections as post effect. Also having realtime GI on. In the log i see also "d3d11: failed to create buffer" few times. It does not matter if the games starts with the nvidia GPU or Intel. I did not have such issues with the forward rendering.

What can i do to investigate this problem?
Windows 10, GTX 1050, laptop

 

Seems to be a problem with unity 2018.3
Just installed the 2019 beta and the error is gone.
Although introducing some flickering to the SSR effect
