Rigidbody interpolation conflicts with transform.position

ok so i was having problems with rigidbody jittering and learned about interpolation but the problem is that turning on interpolation creates conflict between rigidbody addForce and transform.position

how do i fix this?

edit: Basically i cant jump while moving

 void Update()
 {
     var horizontal = Input.GetAxis("Horizontal");
     var vertical = Input.GetAxis("Vertical");
     
     if (isGrounded)
     {
         Jumps = MaxJumps;
     }

     Vector3 forward = Camera.main.transform.forward;
     forward.y = 0;
     transform.position += forward * vertical * Time.deltaTime * speed;

     Vector3 right = Camera.main.transform.right;
     right.y = 0;
     transform.position += right * horizontal * Time.deltaTime * speed;

     if (Input.GetButtonDown("Jump") && Jumps > 1)
     {
         rb.AddForce(new Vector3(0, jumpHeight, 0), ForceMode.Impulse);
         Jumps--;
     }

     isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
 }

}
