It is quite normal for Microsoft Office to occasionally make an add-in inactive or disabled as a result of Office’s extra security. The first step Microsoft Office products take when they crash, is to disable any add ins. If Office suggests that there is an issue with the Create Add-in and asks whether you wish to disable it, always choose No. The Create Add-in will not have caused any problems and you will be able to carry on working normally. If you click Yes, Create will not load and the Create tab will not display on the ribbon. See Create Tab not appearing in Ribbon to re-enable the Create add-in.
