I need help with my third person camera raycast

Here is my code, the camera works correctly and follows the player as I want but the problem is with the raycast part, the camera get stuck on the objects and wont follow the player anymore until I move the mouse to rotate the camera. Hope someone can help me.

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

public class TP_Camera : MonoBehaviour {

 public float minDistance = 5;
 public float maxDistance = 15;
 public float height = 7;
 public float orbitSpeed = 5;
 public float orbitSmooth = 0.05f;
 public float zoomStep = 5;

 private float xAngle = 0;
 private float hInput = 0;
 private float distance = 5;

 private Transform target;

 private Vector3 cameraPos = Vector3.zero;

 private Quaternion rotation;

 void Awake()
 {
     target = GameObject.Find("Player").transform;
     // cameraPos = new Vector3(target.position.x, target.position.y + height, target.position.z - 10);
     //transform.position = cameraPos;
 }
 
 void LateUpdate ()
 {
     hInput = Input.GetAxis("Mouse X");

     //if(Input.GetMouseButton(1))
         OrbitTarget();
     FollowTarget();
 }

 void OrbitTarget()
 {
     Vector3 angles = transform.eulerAngles;
     xAngle = angles.y;

     xAngle += hInput * orbitSpeed * distance * orbitSmooth;

     rotation = Quaternion.Euler(0, xAngle, 0);

 }

 void FollowTarget()
 {
     distance = Mathf.Clamp(distance - Input.GetAxis("Mouse ScrollWheel") * zoomStep, minDistance, maxDistance);
     //THE RAYCAST CODE///////////////////////////////////////////////////
     RaycastHit hit;
     if (Physics.Linecast(target.position, transform.position, out hit))
     {
         distance -= (hit.distance + 1);
     }
     ///////////////////////////////////////////////////////////////////////
     Vector3 negDistance = new Vector3(0, 0, -distance);
     cameraPos = rotation * negDistance + target.position + new Vector3(0, height, 0);

     if (distance > maxDistance)
         distance = maxDistance;

     transform.rotation = rotation;
     transform.position = cameraPos;
 }

 float ClampAngle(float angle)
 {
     if (angle < -360.0f)
         angle += 360.0f;
     if (angle > 360.0f)
         angle -= 360f;
     return Mathf.Clamp(angle, 0, 360);
 }

 float ClampAngle(float angle, float min, float max)
 {
     if (angle < -360.0f)
         angle += 360.0f;
     if (angle > 360.0f)
         angle -= 360f;
     return Mathf.Clamp(angle, min, max);
 }

}
