Logicexception Error When Viewing Existing Workbook after Upgrading to Tableau Server 9.2

Issue

After upgrading to Tableau Server 9.2, an internal error is occurring with a published dashboard that was created in an earlier version of Tableau Server:
 
An unexpected error occurred. If you continue to receive this error please contact your Tableau Server Administrator.

LogicException: Internal Error - An unexpected error occurred and the operation could not be completed.

The error will occur in all browsers for all users--the workbook cannot be loaded.

Environment

Tableau Server 9.2

Resolution

The workbook is corrupted and must be recreated from scratch.

Cause

A workbook may get into a state where certain required elements are missing from the XML, particularly when created in a pre-release (beta) version of Tableau Desktop. Older versions of Tableau Server did not check for this state or throw an error, but more robust XML validation was added in version 9.2, which will refuse to load these damaged files.
