Hi Steve,
I have done both in separate testing I have both did a restore of mail accounts and tested and began from stratch and often times the crash would happen before I was able to use the mail.app at all.
Things I have already tried:
Upon first noticing several mail crashes I continue to click on the reopen and report issue to Apple after Crash report engages.
Restarted the M1-MBA - continued to crash and more often.
Shut down the M1_MBA and restarted up in SafeBoot - continued to crash.
Restarted M1-MBA in regular mode and issue continued to crash.
Turned off all email accounts in System Settings - Internet Account, launch mail.app and immediate crash and report.
System settings - Users and Groups - New Admin test User. Restart M1_MBA and logged into new user account setup email and Mail.app crashed. Restart Mail.app added only iCloud email account. Crash. Only added Gmail account - Crashed. Only added Outlook email account - Crash.
At the suggestion of Apple:
Rebuild mailboxes and test each one individually.
Verified only Apple Software installed no third party apps.
Verified all email accounts were working outside of mail.app (web access) all accounts work outside of Mail.app no crashes.
Shut down M1-MBA and restart into options and erase SSD after a full time machine back up.
Run macOS install of Monterey and set up all email accounts in Mail.app - all email accounts work no issues.
Upgraded to macOS Ventura 13.2 tested email accounts and mail.app crashes before turning any email account back on after testing. Turned on iCloud email account - Crashed, Turned on Gmail email account - Crashed, Turned on Outlook email account - Crashed. Tested each on their own and each one crashed, (from new set up not a restore set up from Time Machine.)
Lastly, by trying another work around, I followed a suggestion to stevefromchandler in the forums from user: DiZoE dated Jan. 30, 2023 11:16PM This was a similar issue I was having except this did not resolve my issue.
Many users have expressed they do not have this issue, however just as many are now claiming they also have this issue. There are also users who have Intel Macs and different Macs such as iMac, MacBook Pros, and Mac Pros who are also experiencing these issues.
It appears that some users including myself are also experiencing problems with External drives such as a DVD Writer by Pioneer, LG that are not being recognized by macOS Ventura (tested on the Mac under VM/Windows 11) the drive works so its not a hardware issue but appears an issue either driver or OS issue. While all the issues I have appear to happen in macOS Ventura they do not cause a problem in Monterey. Monterey is not an option because after upgrading to Ventura it appears the Apple feels the need to add specific security features in Ventura that no longer work in Monterey such as being able to use Apple Pay Wallet on the Mac with Monterey.
In closing this response, keep in mind I have tried just about anything and everything to fix these issues. So many so that I have forgotten what I have already tried but they are in many of the previous posts to this one. I can over look the DVD Writer issue as they could be as simple as a driver update from LG however, the mail.app is a native app made by Apple and the issue is within their own OS and App. Which in turn is forcing me to use Outlook.app instead or access my email via web access, of which none of those work arounds are favorable. While others may not be experiencing these issues at least now it does require a fix from Apple because eventually, everyone will be affected be the glitch.
I have talked to at least 6 Apple Representatives regarding this issue, every one created a ticket and supposedly another rep (tech, who supposed to be a senior tech) calls me back only to find out that senior tech is no more than another Apple advisor who pretty much reads a KB but the issue remains unsolved.
