custom interactions can not use in unity6 [input system version 1.8.2]

Unity Engine
,

I am trying to create a custom interaction according to the manual below

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.8/api/UnityEngine.InputSystem.IInputInteraction.html

the custom interaction runs well at first，but suddenly cause error “No IInputInteraction with name ‘XXX’ has been registered” 。

So confused！！！
I can’t understand why it sometimes runs well and suddenly broken ! !

using UnityEditor;
using UnityEngine;
using UnityEngine.InputSystem;

#if UNITY_EDITOR
[InitializeOnLoad]

public class RepeatInteraction : IInputInteraction
{
    public float repeatDelay = 0.5f;
    public float repeatRate = 0.1f;

    static RepeatInteraction() => InputSystem.RegisterInteraction<RepeatInteraction>();

    [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
    private static void Initialize()
    {
          InputSystem.RegisterInteraction<RepeatInteraction>();
        // Will execute the static constructor as a side effect.
    }

    public void Process(ref InputInteractionContext context)
    {
        Debug.Log("Process");
        var defaultActuation = InputSystem.settings.defaultButtonPressPoint;

        switch (context.phase)
        {
            case InputActionPhase.Waiting:
                if (context.ControlIsActuated(defaultActuation))
                {
                    context.PerformedAndStayStarted();
                    context.SetTimeout(repeatDelay);
                }
                break;

            case InputActionPhase.Started:
            case InputActionPhase.Performed:
                if (!context.ControlIsActuated(defaultActuation))
                {
                    context.Canceled();
                }
                else if (context.timerHasExpired)
                {
                    context.PerformedAndStayStarted();
                    context.SetTimeout(repeatRate);
                }
                break;
        }

        switch (context.phase)
        {
            case InputActionPhase.Waiting: break;
            case InputActionPhase.Started: break;
            case InputActionPhase.Performed: break;
        }
    }

    public void Reset() { }
}
