Same here, as Marcellio, Chris954 - On some of our test machines a Yubikey FIDO2 device on fresh bootup only shows 'sign in options' for last user with no opportunity to input code. It is necessary to either click 'Other User' first then back or switch to password cred provider and back before you can type in the Security Code. Very infuriating as it doesn't affect all machines and upgrading problematic ones to Win10 22H2 doesn't fix either.
Niels Klein The "Interactive logon: Don't display last signed-in" doesn't help in my case and hiberboot is already off for our machines. What does have an effect, strangely, is turning off the LegalNoticeText and LegalNoticeCaption on a machine! In this case the machine always defaults to 'other user' unfortunately but it DOES now display the pin prompt correctly. The last logged on user is listed but not respected as a default and it always defaults to 'other user' but user can at least log on without clicking away. It's also obviously not any kind of fix but would be interested if others find that turning off your company legal notice caption and text at HTLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System changes the situation for you?
