Hey, I have the same problem! I thought I was going nuts or that the USB key (my yubikey!) was going bad, but I have the exact same situation.
Are you running TLP or power savings tuning by any chance?
It could also be a regression from the 3.06 upgrade… see 12th Gen Intel Core BIOS 3.06 Beta where i’ll post a followup comment linking here…
Update: actually, that post explicitely mentions this problem, and a workaround
So I guess I’ll try that next!
