GnuPG version is also needed, maybe it's this problem documented in
/etc/PROBLEMS:

--8<---------------cut here---------------start------------->8---
*** Saving a file encrypted with GnuPG via EasyPG hangs.

This is known to happen with GnuPG v2.4.1.  The only known workaround
is to downgrade to a version of GnuPG older than 2.4.1, or upgrade to
version 2.4.4 and newer, which reportedly solves the problem.  Note
that GnuPG v2.2.42 and later also has this problem, so you should also
avoid those later 2.2.4x versions; v2.2.41 is reported to work fine.
