Unity3D standalone: raycast doesn't work correctly

Hello everyone, I am currently building a vehicle building game, where the player can place or remove blocks using raycast. When I run the scene in the editor it works splendidly however when I build the project and run the scene sometimes it works correctly sometimes it doesn't cast the ray and sometimes it instantiate the block on another block.

The raycast range is set to 50. The main block has a box collider + rigidbody and the other blocks have just box collider and they are the children of the main block

Can some one give a hand?

 if (Input.GetMouseButtonDown(1)) {
                 
                 Ray ray2 = Camera.main.ScreenPointToRay(Input.mousePosition);
                 RaycastHit hit;
                 if (Physics.Raycast(ray2, out hit, 10000)) {
                     con.text += hit.collider.transform.name + Range;
                     if (hit.collider.transform.tag == "part") {
                         Destroy(hit.collider.transform.gameObject);
                     }
                 }
             }
             if (Input.GetMouseButtonDown(0)) {
                 
                 RaycastHit hitPoint;
                 Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
 
                 if (Physics.Raycast(ray, out hitPoint, Range)) {
                     con.text += hitPoint.collider.transform.name + Range;
 
                     bool trigger = false;
                     if (hitPoint.collider.transform.GetComponent<partScript>() != null) {
                         trigger = !hitPoint.collider.transform.GetComponent<partScript>().unplacableObject;
                     }
                     if (trigger || hitPoint.collider.transform.GetComponent<CPU>() != null) {
                         GameObject tmp = Instantiate(Cube, hitPoint.normal + hitPoint.collider.transform.position, Quaternion.identity);
                         tmp.transform.eulerAngles = rotations;
                         roundPosition(tmp);
 
                         if (tmp.GetComponent<partScript>().overwriteRotation) {
                             rotate(tmp.GetComponent<partScript>(), hitPoint, false);
                         }
                     }
                 }
             }
