I updated my computer this morning and now anytime I try and attach an email to an outgoing email, my entire Outlook crashes (before the email attaches and I get a chance to try and send the outgoing email). I've tried restarting Outlook and my computer. I have no problem attaching and sending other types of files. The issue is not limited to one particular email message I'm trying to attach or send -- I've tested the issue, and it has happened with all my tests or various email (.msg) attachments and outgoing emails.
I routinely attach emails from within my Outlook to my outgoing emails in Outlook, by dragging and dropping the email I want to attach to my outgoing email. This is the first time I'm having this issue. I imagine it may have something to do with the update I was forced to run this morning.
Any troubleshooting advice would be much appreciated. Thank you, all!

Here is the formal documentation for this issue, Outlook stops responding when you attach an email .MSG file - Microsoft Support.
Also, if you want to test the code fix for the issue it is now at the Beta Channel which just updated to build 17521.20000 Update History for Office Beta Channel - Office release notes | Microsoft Learn.
Hi, is there a reason this isn't being formally acknowledged anywhere else? We have users in the Semi annual preview channel who are all experiencing outlook crashes but we can't seem to find any clear acknowledgement from Microsoft that this is still an issue.
Thanks for your response.
We are on Semi-Annual Channel Preview, so that explains it and we now have a plan and a timeline.
Much appreciated
Chris,
Are you on Current Channel or Semi-Annual Channel Preview? Current Channel should not repro the issue anymore. For SACP the fix is supposed to go out on April 9th.
This is still happening in 2402 Build 17328.20184.
If I try to add an msg attachment to an e-mail normally, then Outlook crashes.
If I run Outlook in safe mode, the crash still happens when I try to attach an msg file to an e-mail.
If I run Outlook /a <path to the msg file> without Outlook already open, then the problem does not happen and it creates an e-mail with the requested attachment.
However, the above command leaves the Outlook process running and when I run the Outlook /a command again, the second Outlook process causes the same crash to happen when I try to attach an msg file to an e-mail.
The problem also does not happen if I start Outlook disconnected and try to create an e-mail with an msg file attachment while offline. However, if I reconnect and try to add a second msg file attachment to the same e-mail (or any msg attachment to any other e-mail), Outlook crashes.
When the connectivity isn't there, I don't get the "How do you want to attach this file?" prompt, and it seems to be only when I get this prompt and attempt to "Attach as copy" that I get the crash. "Share link" works fine.
Also, Procdump is reporting an Access Violation when watching the crash.
