When I put this coroutine, the function doesn't work ??! Can someone tell why?

public class GameManager : MonoBehaviour
{
    [SerializeField] int moneyCount;
    [SerializeField] item[] items;
    int luckyNum = 7;
    int luckyItemNum;
    int useTime;
    float playerOldMoveSpeed;

    public TextMeshProUGUI playerLifeCountText;

    private GameObject player;
    private PlayerController playerControllerScript;

    // Start is called before the first frame update
    void Start()
    {
        player = GameObject.Find("Player");
        playerControllerScript = player.GetComponent<PlayerController>();
        playerOldMoveSpeed = playerControllerScript.moveSpeed;
    }

    // Update is called once per frame
    void FixedUpdate()
    {
        // If player has lives and is unactive then set him active
        if (player.activeInHierarchy == false && playerControllerScript.playerLifeCount >= 0)
        {
            StartCoroutine(SetPlayerActive());
        }
    }

    public void DropItemIfLucky(Vector2 myPosition, Quaternion myRotation)
    {
        int luckyDrawNum = Random.Range(1, 21);
        if (luckyDrawNum == luckyNum)
        {
            luckyItemNum = Random.Range(0, items.Length);
            if (items[luckyItemNum].name == "CoinX5")
            {
                if(Random.Range(0,2) != 1)
                {
                    luckyItemNum = 0;
                }
            }
            GameObject itemCreated = Instantiate(items[luckyItemNum].itemObject, myPosition, myRotation);
        }
    }

    public void UpdatePlayerLifeCount(int count)
    {
        playerLifeCountText.text = "x " + count;
    }

    IEnumerator SetPlayerActive()
    {
        yield return new WaitForSeconds(1);
        player.gameObject.SetActive(true);
    }

    public void CoinX1Function()
    {
        moneyCount += 1;
        Debug.Log(moneyCount);
    }

    public void CoinX5Function()
    {
        moneyCount += 5;
    }

    public void LifeItemFunction()
    {
        playerControllerScript.playerLifeCount += 1;
        UpdatePlayerLifeCount(playerControllerScript.playerLifeCount);
    }

    public void TeaItemFunction()
    {
        useTime = 16;
        playerControllerScript.moveSpeed = 7;
        StartCoroutine(ItemUseTime());
        playerControllerScript.moveSpeed = playerOldMoveSpeed;
        Debug.Log("All Done");
    }

    public IEnumerator ItemUseTime()
    {
        yield return new WaitForSeconds(useTime);
    }
}

[System.Serializable]
public class item
{
    public string name;
    public GameObject itemObject;
}

The problem is in TeaItemFunction()
When I put ItemUseTime() there it stops working

Any logic you want to run after a coroutine has yielded needs to be inside the coroutine, like this:

public void TeaItemFunction()
{
    useTime = 16;
    playerControllerScript.moveSpeed = 7;
    StartCoroutine(ItemUseTime());
}

public IEnumerator ItemUseTime()
{
    yield return new WaitForSeconds(useTime);
    playerControllerScript.moveSpeed = playerOldMoveSpeed;
    Debug.Log("All Done");
}
