Have you tried replacing (setq epa-pinentry-mode 'loopback) with
(setq epg-pinentry-mode 'loopback)?  If doing this solves your issue,
then I think the problem with the referenced commit [1: 302e500087] is
that it uses define-obsolete-variable-alias (see docstring) in epa.el
after epg-pinentry-mode has already been defined in epg-config.el.

[1: 302e500087]: 2018-05-23 07:53:58 -0400
  Move epa-pinentry-mode to epg-config (Bug#26298)
  https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=302e500087fd4cc1c5f37ec87c98e828b22aaa05

In other words, should we do the following?
