SUDDENLY making sound when unlocking - Samsung Galaxy S23/S23 Ultra

I’ve had my phone for a few months and literally just today it started making this weird beep every time I unlock it. I went through basically everything I could think of, sound settings, vibration, accessibility stuff, notification sounds… even reset all settings. Still happening.

It’s NOT the normal lock/unlock sound. Even if I turn the lock/unlock sound ON, I get the normal sound… and then this extra beep right after. I’m using Nova Launcher + dark mode (but I’ve been using those forever, nothing new)

It just started out of nowhere and now I can’t unhear it 😂

Anyone else on S23 / S23 Ultra getting this? What setting/app could cause a beep on unlock? Any quick things to check (like some hidden accessibility toggle, NFC, routines, a specific app, etc.)?
