Thank you very much for your help! For future reference and people having the same issue: gpg2.3 introduced a new packet type 20 which provides authenticated encryption with associated data (AEAD) [1]. A key generated with gpg2.3 supports this encryption type and encryption in Windows (using the current Gpg4win 4.0.0) defaults to AEAD for a key generated with default settings. Since AEAD/type 20 is not supported yet by version 2.2, decryption on linux distros is not possible using version 2.2.X from their repositories.
