Why are 64-bit libraries not included in GnuPG but Gpg4win?

I don't know (but I respond with hints and repeat the question as HTML emails 
are filtered out by some participants.)

Gpg4win is an official GnuPG distribution for Windows
and it is possible to customise the installation to mainly install GnuPG.
Overal I believe this maybe an oversight, maybe you should file an issue with
dev.gnupg.org.

As far as I know Thunderbird 78+ uses RNP/Botan, and not OpenPGP.js.

Thanks for reporting that this worked fine for you after the right setup!

Most people use Gpg4win, only recently we had to recommed to install
the crypto engine installers over it. So thanks for reporting the issue!
