kSecAttrAccessibleAlwaysThisDeviceOnly behaves differently when we do an icloud restore vs when we transfer from another iphone option during new phone setup, keychain value get erased as expected on icloud restore, but is getting retained when transfer from another iphone option is used

on iOS 14.0 and above if i have two textfields side by side with equal width and equal height constraint , when we try to push a controller containing these textfields the entire UI freezes this is happening on iphone 7 plus and 8 plus devices and randomly on some XR device not all, works on other devices. while debugging the called viewcontroller is executing the didload didappear functions but the viewcontroller doesn't get pushed, i.e the UI deosn't appear on screen, it displays the parent views UI and the entire app freezes, no crash. I am using xibs and  I am using ibdesignables for the textfield Works perfectly fine on iOS 13 and below.
