Microsoft Word stops responding when attempting to use the Open or Save As dialog boxes

When you attempt to use either the Save As or Open dialog boxes in Microsoft Word, the program stops responding.

This is a known issue which Microsoft are currently investigating. Once we have an update from them we will post the information here.

As a workaround, sign out of your Microsoft Office Account. Alternatively, roll-back your Office 365 to version 1911 (Build 12228.20364) or earlier.
