gnupg - Is there a method to decrypt a message without pubring.kbx?

Is there a way to decrypt a message without pubring.kbx?

The problem:

I lost my pubring.kbx and have no usable backups. I still have access to all the other /.gnupg files, including the .key files in private-keys-v1.d, so I am trying to find a way to decrypt a message encrypted with one of my public keys, without access to the original purbing.kbx

What I've attempted:

Importing the private keys from /private-keys-v1.d: gnupg isn't finding any openpgp data in the keygrip.key files to import
File recovery software to restore the lost pubring.kbx
Using gpg --expert --full-gen-key and generating from the existing private .key (option 13)

I have also tried methods listed in this post: https://superuser.com/questions/1537499/accidently-deleted-gnupg-pubring-kbx-how-to-recover-keys
