i used this code for it and the cam just spazed out

using System.Collections;
using System.Collections.Generic;
using Unity.PlasticSCM.Editor.WebApi;
using UnityEngine;
using UnityEngine.AI;
using UnityEngine.InputSystem;
using UnityEngine.UIElements;

public class player_cam : MonoBehaviour
{
public bool isActive = true;
public float mouseSensitivity = 100f; // Sensitivity for mouse movement
public Transform playerBody; // Reference to the player’s body (the GameObject with the Rigidbody)
public Transform cameraTransform; // Reference to the camera
public Rigidbody playerRigidbody; // Reference to the player’s Rigidbody
public float moveSpeed = 5f; // Movement speed

private float xRot = 0f;  
private float yRot = 0f;           // Track the camera's vertical rotation

void Start()
{
    // Lock and hide the cursor
    UnityEngine.Cursor.lockState = CursorLockMode.Locked;
    UnityEngine.Cursor.visible = false;
}

void Update()

{
   if (isActive) {
    xRot+=Input.GetAxis("Mouse Y");
    yRot+=Input.GetAxis("Mouse X");
    xRot += Mathf.Clamp(xRot, -90f, 90f);
    yRot += Mathf.Clamp(yRot, -180f, 180f);

    Camera.main.transform.rotation = Quaternion.Euler(xRot/moveSpeed,yRot/moveSpeed,z:0f);
    
    
    UnityEngine.Cursor.visible = !isActive;

    }
            if (Input.GetKeyDown(KeyCode.Escape)) {
        isActive = !isActive;
    }
    
}

}

Multiply your movement speed by Time.deltaTime. Also, you should only perform camera updates in LateUpdate, not Update.
