Scriptable objects inspector is blank when opening project

I have used the CreateAssetMenu attribute to create scriptableObjects which mainly hold two arrays, I drag the one I want to use in to the inspector of an object in the scene to say which one i want to use.

This all works fine but when I close the project and open it again the inspector for the ScriptableObject is blank unless I modify some code, I have tried a few things to force this but nothing works 100%, for example refreshing the assetDatabase when the project opens, re-importing through the assetDatabase when the project opens and entering play mode when the project opens.

Entering play mode will fix the issue on the latest instance of the scriptableObject that was created but the older versions keep their blank inspector.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEditor;
 using UnityEditor.SceneManagement;
 using UnityEngine;
 
 [CreateAssetMenu(fileName = "House_", menuName = "Standard/House")]
 public class HouseStandard : ScriptableObject
 {
     public int major;
     public int minor;
 
     public string[] bannedNames =
     {
         "box",
         "plane",
         "object",
         "cylinder"
     };
 
     public string[] trueTextureNames =
     {
         // external materials
         "matName1",
         "Matname001"
     };
 
     public string[] househierarchyNames =
     {
         "Cube",
         "Bob",
     };
 }

Above is an image showing what I get in the inspector once the asset is created which is fine, the problem is when i come back to the project the inspector is completely blank with no fields showing.

Any help on this is greatly appreciated!
