VR build where VR doesnt work

I have VR activated using openvr and in editor works fine but once i make the build VR doesnt work, and also i get these errors :

Copying assembly from 'Temp/Obi.dll' to 'Library/ScriptAssemblies/Obi.dll' failed
Copying assembly from 'Temp/Unity.Postprocessing.Runtime.dll' to 'Library/ScriptAssemblies/Unity.Postprocessing.Runtime.dll' failed
Copying assembly from 'Temp/Unity.TextMeshPro.dll' to 'Library/ScriptAssemblies/Unity.TextMeshPro.dll' failed

 

Try deleting Library file and then open your project in Unity.

 

I already did that. I had the same project in another folder, tried that, didnt work. I copied all assets, and not the unity packages like posteffects, to other new project and i get the same errors when try to make a build

 

I see the build sometimes tells me its failed and others successful even though i get those 3 errors anyways. But even when says successful VR doesnt work

 

Found the culprit, it was the asset i bought in the Unity asset store called Obfuscator. Talked to the creator and told me to exclude the htc vive namespace and VR worked. Those namespaces still are there but doesnt affect the build, though i must restart Unity every time i get them.
