Face ID Fail (Position your face within the frame) for iPhone 12 Pro

Hey guys, recently did a housing and screen replacement using genuine parts, I did everything correct and there are no visible signs of damage, however, the Face ID only works when it’s corresponding flex cable bracket is off, doesn’t matter how little or hard I tighten the screws for the bracket, it just says “position your face within the frame”, using the phone without the bracket is a temporary fix, any suggestions? Tried almost everything I can think of.
