Steps to reproduce:
1.) Create a zip archive with 2 or more files
2.) Encrypt zip archive (in my case I used gpg command line tools)
3.) Create an email, attach encrypted zip archive (no need to encrypt the actual message) and send.
I am on a mac, running Big Sur (11.6.7)
In my contrived test, I am running:
gpg (GnuPG/MacGPG2) 2.2.34
libgcrypt 1.8.9
Utilizing the standard mac compression tool.
It should be noted that I've also utilized Ubuntu 18.04, Python 3.8.2 (shutil.make_archive) with gnupg module and the issue remains (I don't think this is a mac problem).
Actual results:
1.) Right click on attachment, select "Decrypt and Save As"
2.) Decompress zip archive (this fails due to file corruption - Inappropriate file type or format)
Expected results:
A proper zip archive would be written to disk, which would permit decompression. It should be noted that if I right click on the attachment and select Save As, the gpg file will be written to disk, I can subsequently decrypt and then unzip the archive and it works fine.
FWIW, this issue is not present in Thunderbird 91.11.0 (64-bit) running on Ubuntu 18.04.

Bug isn't specific to external gnupg - can be reproduced with internal RNP decryption, too.
