            score.text = vr.ToString("F0");
           
            if (vr > PlayerPrefs.GetFloat("HS", 0))

        StartCoroutine(RestartLevel());
    }
    IEnumerator RestartLevel()
    {
        Time.timeScale = 1f / slowness;
        Time.fixedDeltaTime = Time.fixedDeltaTime / slowness;

        yield return new WaitForSeconds(2f / slowness);

        Time.timeScale = 1f;
        Time.fixedDeltaTime = Time.fixedDeltaTime * slowness;


    }
    public GameObject restartPanel;
    public void GameOver()
    {
       
        Invoke("Delay", 1.5f);
        asLost = true;
    }
    void Delay()
    {
        restartPanel.SetActive(true);
        Time.timeScale = 0f;
    }
   public void Restart()
    {

       
        SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
        Time.timeScale = 1;
    }
  

   public void GoToMainMenu()
    {
       
        SceneManager.LoadScene("MainMenu");
        Time.timeScale = 1;
    }
   

}

are you sure that the PlayerPrefs key exists? If it does not exist before you try to read it then it will return a default value, For GetFloat it will return 0f if the key does not exist.
You should check if it exists first before trying to read from it (line 20 in your code) or trying to perform a check against it (line 33 in your code).

Change line 20 to this :

if (PlayerPrefs.HasKey("HS"))
{
    highscor.text = PlayerPrefs.GetFloat("HS", 0).ToString("F0");
}
else
{
    highscor.text = "0";
    PlayerPrefs.SetFloat("HS", 0f);
    PlayerPrefs.Save();
}
