Hi Dominik. I made the same experience when using KeepassWinHello 3.3.1 plugin on a fresh, actual Win 11 install with Keepass 2.6.1. The plugin will no longer work. It uses my camera and recognizes me, but afterwards it will show an error message like "KeepassWinHello.AuthProviderSystemErrorException: NCryptDecrypt, Error Code: 0x80098044..." and not open my database. My current workaround is to downgrade to version 2.60. That works perfectly. KeePassWinHello is the only plugin I use.
