crash when material access renderQueue property

Question

I reset renderer shader after loading mesh from assetbundle. while Unity editor will crash when material access renderQueue property. Unity version 2020.1.6f1

 public static void ResetSharedShader(GameObject go)
         {
             if (go == null) return;
             try
             {
                 Renderer[] renders = go.GetComponentsInChildren();
                 for (int i = 0, length = renders.Length; i < length; i++)
                 {
                     Material mat = renders[i].sharedMaterial;
                     Shader localShader;
                     if (mat != null)
                     {
                         string shaderName = mat.shader.name;
                         **int renderQueue = mat.renderQueue; //here**
                         localShader = Shader.Find(shaderName);
                         if (localShader != null)
                         {
                             mat.shader = localShader;
                             mat.renderQueue = renderQueue;
                         }
                     }
                     Material[] mats = renders[i].sharedMaterials;
                     for (int j = 0; j < mats.Length; j++)
                     {
                         if (mats[j] == null) continue;
                         localShader = Shader.Find(mats[j].shader.name);
                         int matRenderQueue = mats[j].renderQueue;
                         if (localShader != null)
                         {
                             mats[j].shader = localShader;
                             mats[j].renderQueue = matRenderQueue;
                         }
                     }
                 }
             }
             catch(Exception e)
             {
                 UDebug.LogError(e.ToString());
             }
         }
