Problem with Apple Mail
The last time that I use Apple Mail I eliminated the mails in the Junk Mail Folder the app crashed, now every time that I try to start it, the app crashed at 5 seconds.
null-OTHER, macOS High Sierra (10.13.3), (Apple Mail)

It seems like over kill, but there is no stand alone Mail.app—therefore from Recovery I would simply re-install the macOS on top of your existing macOS.
Simply deleting emails from the JUnk folder is not the issue.
