When i change the parent of the object i want to reset its transform but it doesn’t work
here is my code:

using UnityEngine;

public class Reposition : MonoBehaviour
{
    public Transform Myself;
    public void Change()
    {
        Myself.transform.position = new Vector3(0, 0, 0);
        Myself.transform.rotation = new Quaternion(0, 0, 0, 0);
    }
}

If by resetting the transform you mean bringing position and rotation back to the initial global values then this is the code:

    using UnityEngine;
    public class Reposition : MonoBehaviour
    {
        public Transform Myself;
        private Vector3 initialPosition;
        private Quaternion initialRotation;
    
        private void Awake()
        {
            initialPosition = Myself.position;
            initialRotation = Myself.rotation;
        }
    
        public void Change()
        {
            Myself.transform.position = initialPosition;
            Myself.transform.rotation = initialRotation;
        }
    }

If you want to reset the position and rotation to the same position and value relative to the new parent, then this is the right code instead:

using UnityEngine;

public class Reposition : MonoBehaviour
{
    public Transform Myself;
    private Vector3 initialLocalPosition;
    private Quaternion initialLocalRotation;

    private void Awake()
    {
        initialLocalPosition = Myself.localPosition;
        initialLocalRotation = Myself.localRotation;
    }

    public void Change()
    {
        Myself.transform.localPosition = initialLocalPosition;
        Myself.transform.localRotation = initialLocalRotation;
    }
}
