I suspect that the problem is that someone at some moment of time
doesn't have ~/.guix-home/profile/bin in its $PATH and thus it can't
find a pinentry.  Can you show `which gpg`, `which pass`, `which
pinentry`?

$ which -a pinentry
/home/zacchae/.guix-home/profile/bin/pinentry
$ which -a gpg
/home/zacchae/.guix-home/profile/bin/gpg
$ which -a pass
/home/zacchae/.guix-home/profile/bin/pass
$ which -a pinentry
/home/zacchae/.guix-home/profile/bin/pinentry
/home/zacchae/.guix-profile/bin/pinentry
$ which -a gpg
/home/zacchae/.guix-home/profile/bin/gpg
$ which -a pass
/home/zacchae/.guix-home/profile/bin/pass

The gnupg home service from rde project goes a slightly other way and
just sets pinentry-program to absolute path in the store.  Such approach
works with pass well, you can take a look at it for inspiration:
