Getting decryption error : one unknown recipient

Yesterday, I could decrypt the same pgp message with my key and today I can’t… Any idea ?

Hi Ilw,

Do you see your key under the ‘My Certificates’ tab in Kleopatra, or when using the ‘gpg -K’ command in the console? If not, is it possible you are logged in to a different account on your computer? Or is your key on some kind of removable media that is not connected or isn’t being recognized for some reason?
