I am trying to create a confiner for my camera using the bounds of a collider, the issue is that when I hit the wall of the confiner, I need to disable the camera movement, but since I disable it, I now cannot move it at all.

I've tried all I can think of like storing the last "valid" position and restoring it if confiner is hit, but that does not seem to work.

void HandleInput()
    {
        if (inputDisabled)
            return;

        //Speed controls
        if (Input.GetKey(KeyCode.LeftShift))
        {
            movementSpeed = fastSpeed;
        }
        else
        {
            movementSpeed = normalSpeed;
        }

        // Adjust movement speed based on camera zoom
        movementSpeed *= (cameraTransform.localPosition.y / zoomSpeedFactor);

        Vector3 adjustedForward = transform.forward;
        adjustedForward.y = 0;

        //Movement controls
        if (Input.GetKey(KeyCode.W) || Input.GetKey(KeyCode.UpArrow))
        {
            newPosition += (adjustedForward * movementSpeed);
        }
        if (Input.GetKey(KeyCode.S) || Input.GetKey(KeyCode.DownArrow))
        {
            newPosition += (adjustedForward * -movementSpeed);
        }
        if (Input.GetKey(KeyCode.D) || Input.GetKey(KeyCode.RightArrow))
        {
            newPosition += (transform.right * movementSpeed);
        }
        if (Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.LeftArrow))
        {
            newPosition += (transform.right * -movementSpeed);
        }

        //Zoom controls
        if (Input.mouseScrollDelta.y != 0 && !EventSystem.current.IsPointerOverGameObject())
        {
            newZoom -= Input.mouseScrollDelta.y * zoomAmount;
            newZoom.y = ClampValue(newZoom.y, zoomClamp.x, zoomClamp.y);
        }

        if (!collider.bounds.Contains(newPos)) //DISABLE MOVEMENT
            return;

        transform.position = Vector3.Lerp(transform.position, newPosition, Time.unscaledDeltaTime * acceleration);
        cameraTransform.localPosition = Vector3.Lerp(cameraTransform.localPosition, newZoom, Time.unscaledDeltaTime * acceleration);
    }
