Bug / Crash Obi Fluid 6 not render on Window build

[spikebor]

I found a culprit.
This Shader "Obi/URP/Fluid/FluidShading" is added to the AlwaysIncludedShaders list, but somehow still be skipped from build.
The result is this code still create a null material.

Code:

if (fluid_Material == null) fluid_Material= FluidRenderingUtils.CreateMaterial(Shader.Find("Obi/URP/Fluid/FluidShading"));
