I have transparent shader, but after quad with it material all objects with not default sorting layer are unvisible

I'm doing the fog of war in 2d game. But through the material with shader are visible only objects with sorting layer = default. If i changed sorting layer to something else then object disappeared

Some objects have only sprite renderer. Camera is ortographic.

That is shader which i use

 Shader "Custom/FogOfWarCG" {
     Properties {
         _MainTex ("Base (RGB)", 2D) = "white" {}
     }
     SubShader {
         Tags { "RenderType" = "Transparent" "Queue" = "Transparent" }
         Blend SrcAlpha OneMinusSrcAlpha
         Cull Off
         LOD 200
         Lighting off
         
         pass {
             CGPROGRAM
             #pragma vertex vert_img
             #pragma fragment frag
 
             #include "UnityCG.cginc"
             
             uniform sampler2D _MainTex;
             
             fixed4 frag(v2f_img i) : SV_Target {
                 return tex2D(_MainTex, i.uv);
             }
             ENDCG
         }
     }
     FallBack "Diffuse"
 }

Why this happens?
