I have PC and notebook, both Win11 + Thunderbird, on both I have installed certificate from authority, it is installed in Win and also in Thunderbird (only for signing, not for encryption), on notebook everything works fine, on PC there is an error while sending a message: "Message sending failed. You have chosen to electronically sign this message, but the application could not find the corresponding certificate specified in the account settings for mail and discussion groups, or the certificate has expired." Trying different versions of Thunderbird and new profiles, still the same problem. Some suggestions?
