After 14.3.8 Update, Outlook won’t open main window

So I recently installed the 14.3.8 update. After the update, Outlook won't open the main window, but it will let me write new emails and make new calendar appointments, but I can't see if I have any new emails or if my emails have sent, or more. Word & Power Point are also on 14.3.8, but they respond, and will open documents and display new documents, etc. I have tried rebuilding the database and changing the database headers, but that does not work.
