MacMail quits immediately after opening

No problems with Mail until today. Now won't stay open at all. It won't work in Safe Mode either, but stays open a couple seconds longer. Not enough to resolve anything. I turned off the connection to Mail in Preferences/Internet Accounts/ICloud. Mail now works, but of course the Icloud and AOL inboxes are not there. I have also viewed the Library/Containers/ in Finder mode and the com.apple.mail folder is not to be found. There IS a com.apple.MailServiceAgent file. I have considered upgrading to Ventura from Monterey 12.6 to see if this helps. It would prefer to resolve this in Monterey before proceeding with an upgrade. Help is appreciated. Happy New Year to me!

I'm running Ventura 13.2 on a 2021 M1 MBP and, for the past week, Mail quits on launch and will not re-open.


Deleting the email account (in the Mail app) and re-installing it seems to fix the problem for a few days but the crash-on-launch recurred again this morning (so it's not fixed!).


Curiously, MS Outlook is also installed on this machine and it works without fault.


The Mail apps on various other Mac devices work properly (iPhone, iPad, other MBP). So something about this particular app installation and the IMAP filing system I've structured (maybe?).


Mr. Google suggested that there could be a problem with one of the emails I've received/filed but I'm darned if I know how to begin to troubleshoot that (and I don't want to randomly delete dozens of messages).


But the reason I posted this is to let OP know that upgrading to Ventura may not solve his issue.
