Mail Crashing

My mail has developed a regular crash issue which I can't resolve.

I've done a Safe Boot (twice) and run the Disc Utility First Aid.

This is a from the Etrecheck report:

Diagnostics Information (past 7-30 days):

    2020-10-16 13:00:49 Mail.app - Crash (10 times)

        Executable: /Applications/Mail.app

        Details: 

            *** Terminating app due to uncaught exception 'NSRangeException', reas

            on: '*** -[__NSArrayM objectAtIndexedSubscript:]: index 92233720368547

            75807 beyond bounds [0 .. 7]'

            terminating with uncaught exception of type NSException

            abort() called


And a screen shot of part of the report sent to Apple is attached.


All help very much welcomed.

iMac, macOS 10.13

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.
