Since updating from 20191207 to 20200313, a "Press any key to continue ..." interruption appears on every startup of neomutt, regardless of configuration.
Logging with `neomutt -d1` has uncovered the cause: 1) the neomutt config option "crypt_use_gpgme" defaults to yes (see neomutt -D) 2) my installation is compiled without gpgme support (see neomutt -v) If these two collide, neomutt pauses at startup and asks to "Press any key to continue ..." I guess on that screen it should be showing the actual error message: '"crypt_use_gpgme" set but not built with GPGME support' But apparently, the screen is cleared, erasing the message. In effect, only "Press any key to continue ..." is left on screen. neomutt *does* show the error message as expected when running just `neomutt -D`.
Apparently, this has been noticed and fixed upstream, next update should eliminate the problem.
I have updated the port, so it should be fixed now.
