cannot decrypt file symmetric encrypted

[Stefano Tranquillini]

Hi all,
last year I encrypted some files, today i tried to decrypt them but the
decryption fails

stefano@~/Downloads/words$ gpg -d words.1.gpg
gpg: AES256 encrypted data
gpg: encrypted with 1 passphrase
gpg: decryption failed: Bad session key

can it be the difference between 1.4 (i guess in july 2017 that was) and
the current one

stefano@~/Downloads/words$ gpg --version
gpg (GnuPG/MacGPG2) 2.2.8
libgcrypt 1.8.3

what can I do?
(i'm on a mac)
