It seems extremely unlikely you want to be normalizing movement because then even the tiniest controller or input drift would give you full movement.
Print out the values you’re feeding into Move() and ensure they truly are zero.
Perhaps if you must normalize, only do so if the magnitude is above a certain amount (such as 0.1f), otherwise clamp motion to zero.
Also, that’s not quite the right formatting for code posting BTW.
If you post a code snippet, ALWAYS USE CODE TAGS:
