Mac Mail 10.3 keeps crashing on Sierra

Hi,

Since yesterday, my Mac Mail suddenly keeps crashing everytime I open it up.

It keeps alive for around 20-30 seconds, and then closes with the "report / reopen" dialog.

I happened suddenly and on a day where I had been using the mail for the entire day, so as far as I know I haven't done anything to set it up.

All my mails in either a Gmail or a G Suite but unless Google has done something new, I haven't changed any settings.

I'm running Mac Mail 10.3 on Sierra 10.12.6 OS X.

I can provide the Crash Report if necessary.

For the Application Specific Information in the crash report it states that

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'This method should only be called on the serialization queue'

abort() called

terminating with uncaught exception of type NSException

Any suggestions or clue in to what might have caused this and how to fix it would be extremely appreciated.

Cheers

MacBook Air (13-inch Mid 2012), macOS Sierra (10.12.6)

Do a backup, preferably 2 on 2 separate drives.

Quit Mail.

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Go to Library/Containers/com.apple.mail. Move the folder com.apple.mail to your desktop. You must move the entire folder, not just the contents.

Restart, re-launch Mail and test. If the problem is solved, recreate any required Mail settings and import any emails you want to save from the folder on the desktop. You can then put the folder in the Trash. If the problem remains, return the folder to where you got it replacing the one that is there.

If that doesn’t solve it repeat the above using Containers/com.apple.MailServiceAgent.
