Outlook emails get moved to drafts folder as I'm composing the email

As I type an email on my desktop, my Outlook app closes the email and moves it to my Drafts folder. I then have to open up my Drafts folder, open the email, and continue typing. This happens when I've had an email open for 30 seconds or many minutes (e.g., it's not like I've been drafting an email for 30 minutes and have stepped away and Outlook moves it to drafts). I'm often in the middle of typing a sentence and the email disappears and it's gone to Drafts. I then have to go do Drafts and manually reopen the email I was literally just typing. Sometimes it opens immediately, other times it opens and says the email is being edited in another window (which, why???).

It doesn't happen with every email but happens many times per week. A cursory review seems like many people in different environments are having the same issue. I've restarted my computer, all apps are fully updated.
