Resolution

There have been a number of solutions to this issue, listed here in order of likelihood of success based on case reviews:

I. Re-Creating the Tableau Desktop Repository

Ensure all instances of Tableau Desktop are closed
Navigate to the existing Repository location. Most often, this will be .../My Documents/My Tableau Repository
- If the Repository is located on a Network Drive, please move it to a local location, preferably the default My Documents location. Instructions: https://kb.tableau.com/articles/howto/changing-the-my-tableau-repository-location
Rename the existing Repository to "My Tableau Repository.old"
Open Tableau Desktop again - a new Repository should be created automatically
Attempt to open the affected workbook once again

II. Ensure Parity between Tableau Desktop and Tableau Server/Cloud Versions

Review the installed versions of Tableau Desktop and Tableau Server/Cloud
If Tableau Desktop is a different version than Tableau Server/Cloud, please update Tableau Desktop to the closest matching Server/Cloud version. Tableau Release versions and downloads are available on our website here
Republish the affected workbook/datasource from the updated Tableau Desktop version and see if the issue persists

III. Re-Create the Affected Workbook

If the previous methods did not resolve the issue, try to re-create the affected workbook while ensuring parity between Desktop and Server/Cloud versions, and that the repository has been re-created in a suitable location
Republish the recreated workbook/datasource

IV. Review Proxy Settings

If using a Proxy in the environment, please work with your IT team ensure it is configured properly to allow unobstructed traffic from Tableau applications. These settings and recommendations can be reviewed in the following articles:
Required Addresses, Proxies, and Ports
Configuring Proxies for Tableau Server

Cause

The issue may be related to a network issue between Tableau Desktop and Tableau Server/Tableau Cloud or the need to recreate the My Tableau Repository folder.
