Apple says, “Apple has identified an issue where Unlock and Apple Watch may not work on iPhone 13 devices. You may see” Unable to connect to Apple Watch “if you try to unlock your iPhone while you’re wearing a mask, or you might not be able to set the unlock with the Apple Watch. “

However, as far as possible Open with Apple Watch, if the user had their Apple Watch on their wrist and had authenticated themselves, their iPhones could be unlocked using Face ID even with their masks on. It’s a very reasonable part and Apple hopes it won’t take long to provide a fix.
Note that this only affects the iPhone 13 and the older iPhones have nothing to gain.
