Outlook crashes when I attempt to attach an email (.msg) to an outgoing email

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!
