Stencil and mask shader not working when building on Windows Desktop.

Hi! Here is my problem.I'm using a stencil and a mask shader on two game objects.The object with the stencil,masks the object with the mask shader.They're working fine in the editor,but when i build the project for windows desktop,the object with the mask shader is invisible.Any ideas?Thanks!

I am using Unity v5.5.0x1

Windows 10 Professional 64-bit

Graphics Card: GeForce GTX 750 Ti

Here is the Stencil Shader:

 Shader "Custom/Stencil"
  {
      Properties
      {
          _MainTex ("Sprite Texture", 2D) = "white" {}
          _Color ("Tint", Color) = (1,1,1,1)
          [MaterialToggle] PixelSnap ("Pixel snap", Float) = 0
          [PerRendererData]_StencilMask2("Mask Layer", Int) = 1
          [Enum(CompareFunction)] _StencilComp("Mask Mode", Int) = 6
          _TexOpacity("Opacity", Range (0, 1)) = 0.5
          [PerRendererData]_StencilID("Stencil ID", Int) = 1
      }
   
      SubShader
      {
          Tags
          {
