Crashing eMail:

So, Mail opens, and then instantaneously closes? Is that correct? If so, boot in Safe Mode [Hold down command + R] upon boot. Log in for 30 seconds, and then restart, logging in normally.

If still no good Disconnect from the Internet, then start Mail, look for the last rec'd eMail.

Does Mail crash if no internet?

Quit Mail & login to your WebMail in a Browser, if possible delete any later eMails there after the last rec'd one on the Mac.

If you have no POP accounts & they’re all IMAP accounts then in Mail’s Mailbox menu choose Rebuild.
