Black texture on Android (shader)

Moved my project to Unity 2020.2. 1f1. After loading the project, some materials (with specific shaders) are rendered black, but only on my Android devices (In editor is ok) What could be the problem? I read a lot of solutions, for example to change the project settings, graphics settings for Android, but no one of them not helped. The code of the problematic shaders:

Shader "XRay"

 Properties
         {
                 _Color("Color", Color) = (0.26,0.19,0.16,0.0)
                 _Offset("Offset", Range(0.0,1.0)) = 0.0
                 _Scale("Scale", Range(0.0,10.0)) = 1.0
                 _RimPower("Rim Power", Range(0.1,8.0)) = 3.0
         }
         SubShader{
                 Cull Back
                 ZWrite Off
                 Blend OneMinusDstColor One // Soft Additive
 
                 Tags { "RenderType" = "Transparent"  "Queue" = "Transparent" }
 
                 CGPROGRAM
                 #include "HoloCP.cginc"
 
                 #pragma surface surf Lambert
 
                 struct Input {
                         fixed3 viewDir;
                         fixed3 worldPos;
                 };
 
                 fixed4 _Color;
                 fixed _Offset;
                 fixed _Scale;
                 fixed _RimPower;
                 void surf(Input IN, inout SurfaceOutput o) {
                         half rim = 1.0 - saturate(dot(normalize(IN.viewDir), o.Normal));
                         o.Emission = saturate(_Color.rgb * (_Offset + _Scale * pow(rim, _RimPower)));
                 }
                 ENDCG
         }

P.S. everything worked before that
