Booleans cannot be changed between scripts in Unity

Question

In my game there is a game manager that interacts with all players and is able to change whether a player is actionable by accessing their script. However, the Game manager script simply refused to change the actionable bool. There were no errors produced either. Even changing all of the private variables to public didn't change anything. What am I doing wrong?

My player script:

public class PlayerManager : MonoBehaviour
{
    public bool actionable;

    void Start()
    {
        actionable = false;
    }
}

My Game Manager Script:

public class GameManager : MonoBehaviour
{
    private PlayerManager playerScript;
    public List<GameObject> players = new List<GameObject>();
    private GameObject currentPlayer, seats;
    private int turn;

    void Start()
    {
            
        turn = 0;
        currentPlayer = players[turn];
        playerScript = currentPlayer.GetComponent<PlayerManager>();
        playerScript.actionable = true;
    }
}
