MissingReference after removing component from gameObject

Hi guys. When I am trying to remove a component from my gameobject (doing it via script), I got an error. My code:

 public class Test: MonoBehaviour
 {
     private MeshFilter m_Filter;
 
     public void createMesh()
     {
         if (m_Filter == null)
         {
             m_Filter = gameObject.AddComponent<MeshFilter>();
         }
     }
 
     public void removeMesh()
     {
         if (m_Filter != null)
         {
             if (Application.isEditor)
                 DestroyImmediate(m_Filter);
             else
                 Destroy(m_Filter);
         }
     }
 }

and editor script for this:

 [CustomEditor(typeof(Test))]
 public class TestEditor: Editor
 {
 
     new public Test target
     {
         get
         {
             return base.target as Test;
         }
     }
 
     public override void OnInspectorGUI()
     {
         base.OnInspectorGUI();
 
         if (GUILayout.Button("Create mesh"))
         {
             target.createMesh();
         }
 
         if (GUILayout.Button("Remove mesh"))
         {
             target.removeMesh();
         }
     }
 }

and after clicking "remove mesh" button, mesh get removed, but then exception pops:

after I double-click on exception in console, editor shows next window:

Thanks for help in advance.
