I can forgive you for your english but I’ll never forgive you for that ambiguous title.

Looks like you can’t find the Gameovertext component. Have you double checked that you have it in inspector?

Yes i have.
but is line 15 not 17

You pasted 17 in OP.
Anyway GetComponent will only work if all of those

GetComponent<Highscoresaver>().HighScore();
GetComponent<PlayerMovement>().enabled = false;
GetComponent<Gameovertext>().Gameover();
GetComponent<Taptext>().Texttap();
GetComponent<Generator>().enabled = false;

are compoments of (presumably) Player GameObject.
But are they?
If not, you’ll have to point to the GameObject that houses those components and access them that way.

using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;
 
public class PlayerCollision : MonoBehaviour
{
    public PlayerMovement movement;
    public Text gameover;
    public Highscoresaver highscore;
 
    private void OnCollisionEnter(Collision collisionInfo)
    {
        if (collisionInfo.collider.tag == "Barrier")
        {
            GetComponent<Highscoresaver>().HighScore();  //this works becouse you have a Highscoresaver script on this gameObject
            GetComponent<PlayerMovement>().enabled = false; //this works becouse you have a PlayerMovement script on this gameObject
            GetComponent<Gameovertext>().Gameover(); // there is no Gameovertext script on this gameObject.  you might need to do GameObject.FindWithTag("name of the object").GetComponent<Gameovertext>().Gameover();
            GetComponent<Taptext>().Texttap(); // this might fail too.  GameObject.FindWithTag("name of the object").GetComponent<Taptext>().Texttap();
            GetComponent<Generator>().enabled = false; // this might fail too. GameObject.FindWithTag("name of the object").GetComponent<Generator>().enabled = false;
            Debug.Log("RIP");
        }
    }
}
