Outlook locks up when opening "Manage Rules & Alerts"


Outlook version

Windows 10, Outlook 2016.
I open up 4 email accounts when I launch Outlook. Office365, Hotmail, a personal one and one with a group that I help with.
This week, I found that some rules (that run VBA scripts) didn't run. Normally, I just go and run the rules manually. (Normally, windows decides to restart and I have to log in again)
However, this week when trying to go to Manage Rules & Alerts, it frequently will just do nothing. After a short while, the mouse changes from the pointer. Sometimes Outlook dims. Other times, the Manage Rules dialog does open, but going to Run Rules Now does the same thing. In any event, the "Run on this Computer" rules are not running.

I have tried removing a lot of the rules (most are on the Office365 account - I logged in manually and just deleted a bunch that I hope I can consolidate), but this still happens.

Any help in figuring this out would be gratefully appreciated. This is greatly affecting my productivity.

Update: After a reboot of the computer, the rules do run. However, this issue of not being able to go into Manage Rules is still existing. Does anyone have any idea on this?

In my profile, I have 4 accounts. 2 are exchange accounts (one O365, one Hotmail). The other two accounts are personal email accounts; one is IMAP, one is POP3. There are no shared mailboxes in the profile.
