Question Players Rotation keeps snapping back to original rotation (Controller Input)

Hey, i am trying to make Twin Stick Controller Movement for a Top Down 2D game, i have controller Inputs and movement set up already, but when rotating the character with the right stick, it seems to snap the rotation back, as soon as i let go of the right stick, everything else seems to work just fine, the player rotates correctly with the right stick, just when i stop rotating it, it snaps the rotation back

here is my code for the rotation:

Code (CSharp):

1.  
2. float RsHorizontal = Input.GetAxis("RSHorizontal");
3. float RsVertical = Input.GetAxis("RSVertical");
4.  
5. if (RsHorizontal != 0 || RsVertical != 0)
6. {
7.        float controllerangle = Mathf.Atan2 (RsHorizontal, RsVertical) * Mathf.Rad2Deg - 90;
8.        rb.MoveRotation(controllerangle);
9. }
10.  

i added the -90 to the rotation angle so the starting position of my sprite would be correct

any help is appreciated,
thanks!
