mail crashing

This has been happening a couple times a week for better than 6 months now. I keep sending the crash report to Apple but I guess they have better things to do. I've searched here and don't see any recent posts from others experiencing this issue. Any help would be appreciated. Below is the beginning of the crash report, I have more but didn't want to send that large a post if not needed.

Yeah, that's what I was asking.

One thing that can crash Mail on the Mac is an incoming Malformed eMail, but tough to track down....

Quit mail.

Finder>Go>Go to Folder, copy & Paste:

~/Library/Containers/com.apple.mail

Highlight all the contents.

Then right-click and choose "New Folder with Selection”. Do not move the new folder from this current location.

You can close the Finder window.

The next step will be to restart the Mac and test

After the computer is restarted, open the Mail to see if it runs properly.

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?

 Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.

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

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.

I'm not sure what you mean. After it crashes, I send the report, and I start it back up again it runs normally until the next crash.

FIY I just did a "clear saved state" and a manual rebuild of mail to see if that resolves it, an automatic rebuild did not solve the problem.

My Mail isn't crashing to the point that it quits, but it gets hung up multiple times a day, and moves my inboxes around into a different order. Gmail inboxes seem to be affected, but not Exchange ones. I have to quit Mail, and often force quit, and then when I get back in it's ok for a bit. Driving me nuts and Apple Support hasn't been able to figure it out - I'm testing now to see if Catalina 10.15.3 fixes it, and I thought it had, but now it's happened again. Not sure if any of this is the same as what's happening to you.
