I see.

Thank you for the log.

Here, it seems for me that your file (j.pgp) is malformed.
Type=9 is the encrypted data packet, but its length is 0.

Since OpenPGP format for the encrypted data packet begins with a
block-size of random bytes.  So, length 0 should not be happened.

I think that this is the cause of your trouble.

Note that the length of the encrypted data packet is data before
decryption, passphrase doesn't matter here.

Yes.
