shader disables because not supported

so ive been working on a blur shader recently and for some reason it isnt working and if i remove the isSupported check, it gives me a "Too many passes error"

here is the main script

BlurBehind.cs using System; using UnityEngine; [AddComponentMenu("Image Effects/Blur Behind"), ExecuteInEditMode, RequireComponent(typeof(Camera))] public class BlurBehind : MonoBehaviour { private static RenderTexture blurredTexture; private static Material blurMaterial; private static int count; [SerializeField] private Shader blurShader; [Header("Downsample"), Range(0f, 2f)] public int power = 1; [Header("Blur"), Range(0f, 25f), Tooltip("Blur radius in screen height percents")] public float radius = 5f; [Range(1f, 4f), Tooltip("Gaussian blur iterations.

and here is the shader:
