I did not install MacGPG. Then when I signed the email using the private key in my Yubikey, the following appeared. This problem does not occur if I don't customize the installation. What should I do? ? Thank you

    Hi Hao,

    can you explain why you do not want to use MacGPG that comes with GPG Suite?

    Otherwise, does your problem persists after a restart?
