An error occurs in OpenGL/Vulkan only

[jiaozi158]

I am currently using Unity 2021.2.0f1 ( URP 12.1 ).

( If not excluding the OpenGL Core and ES 3 API. )

There will be a compilation error when using OpenGL Core/Vulkan as target Graphics API.

But after deleting this structure in Common.hlsl, the error disappears. The shader ( tested Fin only ) works as expected.

I cannot find out which line occurs the error.
Can this error be fixed?
