I've configured an external gpg key for use in Thunderbird, but I'm unable to decrypt an encrypted message sent to myself via thunderbird. I've attached the error thunderbird gives me.

Sending a normal email, a signed email and an encrypted email works just fine. Verifying a signed email also works fine.

Extracting the GPG message, and attempting to manually decrypt it via gpg gives me the following error:

$ gpg --decrypt enc.txt gpg: encrypted with cv25519 key, ID 0xREDACTED, created 2020-01-01 

     "REDACTED"

gpg: encrypted with cv25519 key, ID 0xREDACTED, created 2020-01-01 

     "REDACTED"

gpg: [don't know]: invalid packet (ctb=2d) gpg: [don't know]: invalid packet (ctb=2d)

I followed the instructions here to setup my YubiKey OPGP w/ Thunderbird: https://wiki.mozilla.org/Thunderbird:OpenPGP:Smartcards#Configure_an_email_account_to_use_an_external_GnuPG_key
