ScriptableObject with C# event not working in unity editor, but working in build, is there an explanation as to why?

Unity version is 2021.3.0f1 LTS. I have a Scriptable Object that contains a c# event and a couple methods to add, remove, and clear listeners. Yesterday, the project worked as intended in the unity editor where if the c# event was invoked, the listeners would then execute, but now, whenever I try to execute it, nothing happens. So I tried creating a build to see if it would work there, and it does. Any explanation to this? Are c# events not very compatible with scriptable objects? This is my code:

 public class RSEvent : ScriptableObject
         {
             #region Simple
     
             private event Action _simpleEvent;
     
             public void Invoke()
             {
                 _simpleEvent?.Invoke();
             }
     
             public void AddListener(params Action[] listeners)
             {
                 foreach (Action listener in listeners)
                 {
                     _simpleEvent += listener;
                 }
             }
     
             public void RemoveListener(params Action[] listeners)
             {
                 foreach (Action listener in listeners)
                 {
                     _simpleEvent -= listener;
                 }
             }
     
             #endregion
     
             #region Complex
     
             private event Action<object> _complexEvent;
     
             public void Invoke(object args)
             {
                 _complexEvent?.Invoke(args);
             }
     
             public void AddListener(params Action<object>[] listeners)
             {
                 foreach (Action<object> listener in listeners)
                 {
                     _complexEvent += listener;
                 }
             }
     
             public void RemoveListener(params Action<object>[] listeners)
             {
                 foreach (Action<object> listener in listeners)
                 {
                     _complexEvent -= listener;
                 }
             }
     
             #endregion
         }
