Enigmail 2.0.6 Failing to Decrypt in Thunderbird (52.7.0)

[Andrew]

My enigmail worked perfectly until recently, with no obvious changes causing the issue. When I try to decrypt an encrypted email, I receive the error message "Bad Passphrase"

I am able to copy the message to the clipboard, and using GnuPG directly, am able to decrypt the message properly, with the passphrase, so the key works and GnuPG works. Anyone have any ideas on why this is now failing in enigmail, when it used to work?

Thank you.

I can tell you for certain that nothing changed in Enigmail, especially as passphrase management is done by gnupg/gpg-agent and not by Enigmail

Any suggestions on how I can try and troubleshoot and correct this?
