Windows Hello face unlock immediately relocks, reprompts

I don’t see anyone else reporting this, so I presume this is some weirdness on my new Win 11 laptop. Hoping for suggested fixes, though.

When I launch the Desktop version, there’s a very short delay, then I see the Windows Hello prompt. The camera scans my face, and unlocks BitWarden as expected (except, why do I need to click a button to approve?). Unfortunately, about 50% of the time, after about 2 seconds the app locks itself again, then again shows the Windows Hello prompt. The app again unlocks after the camera re-scans me, and this time stays unlocked.

I swear I’m not clicking anything, this happens with hands off the mouse and keyboard. Anyone have any clues what’s going on?
