Camera Locking In Builds

Getting Started

My camera feels like it snaps back into place when I try to move it left and right. This only happens in builds, can anyone help? This is my script:

using UnityEngine;

public class PlayerLook : MonoBehaviour
{
public float mouseSensitivity = 100f;
public Transform playerBody;

private float xRotation = 0f;  
private bool isInventoryOpen = false; // Track inventory state  
private const string SensitivityKey = "MouseSensitivity";  

void Start()  
{  
    if (playerBody == null)  
    {  
        playerBody = transform.parent;  
        if (playerBody == null)  
        {  
            enabled = false;  
            return;  
        }  
    }  

    // Load saved sensitivity or use default  
    mouseSensitivity = PlayerPrefs.GetFloat(SensitivityKey, mouseSensitivity);  

    LockCursor();  
}  

void Update()  
{  
    if (isInventoryOpen) return; // Skip look logic when inventory is open  

    float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;  
    float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;  

    xRotation -= mouseY;  
    xRotation = Mathf.Clamp(xRotation, -90f, 90f);  
    transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);  

    playerBody.Rotate(Vector3.up * mouseX);  
}  

public void SetInventoryState(bool isOpen)  
{  
    isInventoryOpen = isOpen;  

    if (isInventoryOpen)  
    {  
        UnlockCursor();  
    }  
    else  
    {  
        LockCursor();  
    }  
}  

public void SetMouseSensitivity(float sensitivity)  
{  
    mouseSensitivity = sensitivity;  

    // Save sensitivity to PlayerPrefs  
    PlayerPrefs.SetFloat(SensitivityKey, sensitivity);  
    PlayerPrefs.Save();  
}  

private void LockCursor()  
{  
    Cursor.lockState = CursorLockMode.Locked;  
    Cursor.visible = false;  
}  

private void UnlockCursor()  
{  
    Cursor.lockState = CursorLockMode.None;  
    Cursor.visible = true;  
}

}
