Windows 10: Can't enter pin in Windows 10 1903 (pretty sure)

When I was booted up my PC after a update, for some reason, it didn't let me log in with my pin and said "You've entered your pin too many times incorrectly. Reboot the PC to try again.", even though I hadn't entered my pin yet to sign in. When I rebooted the PC, the message was still there. Thankfully, it still let me sign in with my password. Is there a way around this?

Can't enter PIN for Headset

Bluetooth Plantronics PR BT5028. Windows V 1903. Windows recognizes the headset when I try to add it, but then puts up a window suggesting a six-digit number and asking if that number matches the headset PIN.
Plantronics has publicly posted the fact that the PIN is "0000" but....there is no way I can find to enter 0000. When Windows decides that the numbers don't match the pairing fails and another six-digit number is offered.
Has anyone encountered this before? How can I enter the known pin?

 

Can't enter PIN for Headset

I'm grateful for your replies. I obviously haven't done a good job of explaining. Here are snips of the windows involved. I have done all the steps suggested, but I can't directly enter the PIN in the larger window. That seems to be my only problem. Plantronics hasn't answered yet, but I'll hope they come through.
