can anyone tell me why i am getting this error

i am getting this error , what might be wrong in my script;This is a GameManget.cs script

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class GameManager : MonoBehaviour
6. {
7. public static GameManager singleton;
8. public bool GameStarted { get; private set; }
9. public bool GameEnded { get; private set;}
10.  
11.  
12. // Start is called before the first frame update
13. private void Awake()
14. {
15. if (singleton == null)
16. {
17. singleton = this;
18. }
19. else if(singleton != this)
20. {
21. Destroy(gameobject);
22. }
23. }
24.  
25. public void StartGame()
26. {
27. GameStarted = true;
28. Debug.Log("Game Started");
29. }
30.  
31. public void EndGame(bool win)
32. {
33. GameEnded = true;
34. Debug.Log("Game Ended");
35.  
36. if (!win)
37. {
38. //Restart the game
39. Invoke("RestartGame",2);
40. }
41. }
42.  
43. public void RestartGame()
44. {
45. UnityEngine.SceneManagement.SceneManager.LoadScene(0);
46. }
47.  
48.  
49. }
50.  

And this is the scrpt for my ball controller

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Ballcontroller : MonoBehaviour
6. {
7.  
8. [SerializeField] private float thrust = 150f;
9. [SerializeField] private Rigidbody rb;
10. [SerializeField] private float wallDistance = 5f;
11. [SerializeField] private float minCamDistance = 3f;
12.  
13. private Vector2 lastMousePos;
14.  
15. // Update is called once per frame
16. void Update()
17. {
18. Vector2 deltaPos = Vector2.zero;
19.  
20. if(Input.GetMouseButton(0))
21. {
22. Vector2 currentMousePos = Input.mousePosition;
23.  
24. if(lastMousePos == Vector2.zero)
25. lastMousePos = currentMousePos;
26.  
27. deltaPos = currentMousePos - lastMousePos;
28. lastMousePos = currentMousePos;
29.  
30. Vector3 force = new Vector3(deltaPos.x, 0, deltaPos.y) * thrust;
31. rb.AddForce(force);
32. }
33. else
34. {
35. lastMousePos = Vector2.zero;
36. }
37. }
38.  
39. private void FixedUpdate()
40. {
41. if (GameManager.singleton.GameEnded)
42. return;
43.  
44. if (GameManager.singleton.GameStarted)
45. {
46. rb.MovePosition(transform.position + Vector3.forward * 5 * Time.fixedDeltaTime);
47.  
48. }
49. }
50.  
51. private void LateUpdate()
52. {
53. Vector3 pos = transform.position;
54.  
55. if(transform.position.x < -wallDistance)
56. {
57. pos.x = -wallDistance;
58. }
59. else if(transform.position.x > wallDistance)
60. {
61. pos.x = wallDistance;
62. }
63.  
64. if(transform.position.z < Camera.main.transform.position.z + minCamDistance)
65. {
66. pos.z = Camera.main.transform.position.z + minCamDistance;
67. }
68. transform.position = pos;
69. }
70.  
71. private void OnCollisionEnter(Collision collision)
72. {
73. if(GameManager.singleton.GameEnded)
74. return;
75.  
76. if(collision.gameObject.tag == "Death")
77. GameManager.singleton.EndGame(false);
78. }
79.  
80. }

Theres no such thing as "gameobject", MB has a field called "gameObject" that points to the game object the script is attached to.
