Custom Shader not working on build (Windows and URP)

Hello! I have a shader that i made using the Shader Graph for a simple dither effect:

On the editor is working as intended, but in my build i only see a pink color, like when there is a missing texture, is there something i might need to set different in the settings?

Also, im calling the material with this shader in a OnTriggerEnter script like this

 using UnityEngine;
 
 private Renderer ditherRender;
 public GameObject WestDoor;
 public Shader shader2;
 
 private void OnTriggerEnter(Collider other)
     {
     if (other.tag == "WDoor_I")
         {
             ditherRender = WestDoor.GetComponent<Renderer>();
             ditherRender.material.shader = shader2;
         }
     }

Thanks in advance for reading and your time.
