Graphics API error with Unity XR

I'm having a problem with building using Unity XR plugin. I get an error saying that 'D3D11 is the only Graphics API compatible with desktop platforms'. I am told to go into player settings to change this - so I disable 'auto graphics API' and the default API listed is Direct3D11. I am assuming this is the same one as D3D11, and thus correct!!!

Can anyone tell me what' I'm doing wrong?

 

Could you be more specific as to what type of application you are trying to build on Desktop ? Some plugins require specific graphics API. For example ARCore on Android requires OpenGLES.
