Circle Cutout Shader is working in one eye and not in another eye in HoloLens 2 Device

Circle Cutout Shader is working in one eye and not in another eye in HoloLens 2 Device. Please help if possible and suggest the needful to change the shader into multipass.

Code :

 Shader "Custom/CircleCutout" 
 {
     Properties 
     {
        _MainTex ("Sprite Texture", 2D) = "white" {}
        _Color("Tint / Transparency", Color) = (1,1,1,1)
        _CutTint("Cut Tint / Transparency", Color) = (1,1,1,0)
        _CutOffX("Cut Offset X", Float) = 0.50
        _CutOffY("Cut Offset Y", Float) = 0.50
        _Radius("Cut Radius", Float) = 0.50
        _BlurWidth("Edge Blur Width", Float) = 1
        [MaterialToggle] PixelSnap ("Pixel snap", Float) = 0
     }
     SubShader 
     {
         Tags
         { 
             "Queue"="Transparent" 
             "IgnoreProjector"="True" 
             "RenderType"="Transparent" 
             "PreviewType"="Plane"
             "CanUseSpriteAtlas"="True"
         }
              Cull Off
             Lighting Off
             ZWrite Off
             Fog { Mode Off }

     } 
 Fallback "Transparent/VertexLit"

Thanks in advance.
