Question trouble with collision

basically, if i try to move forward near the very top of something, i end up getting to fly inside it, until i walk outside of it. my game is a 3rd person camera-relative parkour game. anyone able to figure out how i can fix this? my code is below, and a picture of the issue is attached.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PlayerMovement : MonoBehaviour
6. {
7.     public CharacterController controller;
8.     public Transform cam;
9.  
10.     public float speed = 6f;
11.     public float gravity = -9.81f;
12.     public float jumpHeight = 3f;
13.  
14.     public Transform groundCheck;
15.     public float groundDistance = 0.4f;
16.     public LayerMask groundMask;
17.  
18.     Vector3 velocity;
19.     bool isGrounded;
20.  
21.     public float turnSmoothTime = 0.1f;
22.     float turnSmoothVelocity;
23.  
24.     private void Start()
25.     {
26.  
27.     }
28.  
29.     // Update is called once per frame
30.     void Update()
31.     {
32.  
33.         isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
34.  
35.         if (isGrounded && velocity.y < 0)
36.         {
37.             velocity.y = -2f;
38.         }
39.  
40.         float horizontal = Input.GetAxisRaw("Horizontal");
41.         float vertical = Input.GetAxisRaw("Vertical");
42.         Vector3 direction = new Vector3(horizontal, 0f, vertical).normalized;
43.  
44.         velocity.y += gravity * Time.deltaTime;
45.  
46.         controller.Move(velocity * Time.deltaTime);
47.  
48.         if (Input.GetButtonDown("Jump") && isGrounded)
49.         {
50.             velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
51.         }
52.  
53.         if (direction.magnitude >= 0.1f)
54.         {
55.             float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg + cam.eulerAngles.y;
56.             float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime);
57.             transform.rotation = Quaternion.Euler(0f, angle, 0f);
58.  
59.  
60.  
61.             Vector3 moveDir = Quaternion.Euler(0f, targetAngle, 0f) * Vector3.forward;
62.             controller.Move(moveDir.normalized * speed * Time.deltaTime);
63.         }
64.     }
65. }

 

You should wrap your code in a Code Block first for better readability:
