  *** Saving, via EasyPG, a file encrypted with GnuPG 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, in the
  future, upgrade to a newer version which solves the problem, when such
  a fixed version becomes available).

IOW, this is not an Emacs bug, this is a misfeature in GnuPG 2.4.x,
hopefully to be fixed soon on their side.
