iPhone 14 Pro - Face ID constantly requiring passcode to activate

I get this message at least 4-5 times per day: "Your passcode is required to enable Face ID".

I am aware there are certain conditions in which iOS will require a passcode, and I am not triggering these conditions.

I have tried everything (including a fresh install from a laptop). The phone has even been replaced under AppleCare.

My best guess is that notifications are triggering the Face ID module to scan, which is causing Face ID failures. I have actually seen this happen (notification comes in, the lock on the dynamic island shakes which indicates Face ID is attempting to scan). But other than turning notifications off, I cannot find a solution to this problem.
