How can I fix error CS1026: `)` expected

Dear all I have a problem on coding Rigidbody movement, please help.

using System.Collections;
using System.Collections.Generic;
using System.Diagnostics;
using UnityEngine;

[DebuggerDisplay($@"{{{nameof(DebuggerDisplay)}(),nq}}")]
public class NewBehaviourScript : MonoBehaviour
{
    public float yaw = 0.0f, pitch = 0.0f;
    private Rigidbody Rb;

    [Serializefiled] float walkspeed = 0.0f, sensitivity = 2.0f;

    void Start()
    {
        Cursor.lockstate = CursorLockMode.Locked;
        rb = gameobject.GetComponet<Rigidbody>();
    }

    void Update()
    {
        if (!Input.Getkey(keycode.Space) || !physics.Raycast(rb.tranform.position, Vector3.down, 1 + 0.001f))
        {
        }

        else
            rb.velocity = new Vector3(rb.velocity.x, 5.0f, rb.velocity.z);
        Look();
    }

    private void Fixedupdate() => Movement();
