Why does my character pass through walls when he respawns and I lose control of him?

I am working on a 2d platformer and when I respawn my character falls and passes through everything. This is my respawn script
`private void Awake() {
instance = this;
}
public void Respawn () {
Instantiate(Chip, respawnPoint.position, Quaternion.identity);

}
}
`

hey , maybe the character that gets instantiated does not have any of your components attached to it ? have you checked that? and also maybe make a prefab of your character and try to instantiate the prefab.

I also recommend instead of instantiating the character you could deactivate the character using gameobject.setactive(false) and then change it’s position to the respawn position and then active the character using gameobject.setactive(true);

It has the components all on it which is what confuses me and my character is a prefab

I tried making it but now it just gets rid of the guy and I got rid of the destroy character

   Death:
 private void OnCollisionEnter2D(Collision2D collision) {
    if (collision.gameObject.CompareTag("Spikes")){
        LevelManager.instance.Respawn();
}
    }

Respawn:
public void Respawn () {
     gameObject.SetActive(false);
     transform.position = new Vector3(44.5f,19.3f,-0.9598976f);
     gameObject.SetActive(true);
     
 }
