Resolution Note:
After the investigation, we decide to close this case as "by-design"
Soft particles used in the project requires depth texture data as documented in this page(https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@13.1/manual/particles-lit-shader.html)
However, the pipeline asset used in the project did not enable the depth texture
Confirmed locally that enabling depth texture fixed this issue. Another way to fix it is to disable the soft particle.
