[Solved] shader error on Android(Oculus Quest) build

[Snail921]

Hi,

I started getting errors on compiling the project for Oculus Quest.
Here is the errors:

1. Shader error in 'Obi/Particles': invalid subscript '_ShadowCoord' at line 92 (on gles3)
   
   Compiling Vertex program with DIRECTIONAL SHADOWS_SHADOWMASK LIGHTPROBE_SH
   Platform defines: UNITY_NO_DXT5nm UNITY_NO_RGBM UNITY_ENABLE_REFLECTION_BUFFERS UNITY_FRAMEBUFFER_FETCH_AVAILABLE UNITY_NO_CUBEMAP_ARRAY UNITY_NO_SCREENSPACE_SHADOWS UNITY_PBS_USE_BRDF2 SHADER_API_MOBILE UNITY_HARDWARE_TIER2 UNITY_LIGHTMAP_DLDR_ENCODING
   
   
   
2. Error building Player: Shader error in 'Obi/Particles': invalid subscript '_ShadowCoord' at line 92 (on gles3)
   
   Compiling Vertex program with DIRECTIONAL SHADOWS_SHADOWMASK LIGHTPROBE_SH
   Platform defines: UNITY_NO_DXT5nm UNITY_NO_RGBM UNITY_ENABLE_REFLECTION_BUFFERS UNITY_FRAMEBUFFER_FETCH_AVAILABLE UNITY_NO_CUBEMAP_ARRAY UNITY_NO_SCREENSPACE_SHADOWS UNITY_PBS_USE_BRDF2 SHADER_API_MOBILE UNITY_HARDWARE_TIER2 UNITY_LIGHTMAP_DLDR_ENCODING
   

I did not get any errors before and have no idea why the project starts throwing errors.
Could you please give me a solution for this?
