Windows 10: I can no longer connect my bluetooth K380 Logitech keyboard

My Logitech keyboard is not connecting this morning. I've been using it for years, first on W10, now W11. It's an easy hookup but when I enter the 6 digit code, I receive the message "That PIN didn't work try connecting again."My husband has the same keyboard but I shut his off while I tried to pair up my keyboard to my laptop, and received the same message. Any guidance would be helpful. Joan
