Workbook Thumbnail Images Missing from Home Page

When you open Tableau Desktop, the thumbnails on the home age might be blank instead of displaying a workbook preview.

In addition, the following entry might appear in the Tableau Desktop log files:

Error loading bitmap: C:\Users\<USER>\AppData\Local\Temp\TableauTemp\<Random_Characters>\thumb0.pngs

One of the following troubleshooting steps might solve the issue:

Add Tableau Desktop related processes to the trusted applications list for antivirus.
Add the TableauTemp folder to the antivirus exclusions list (C:\Users\<user>\AppData\Local\Temp\TableauTemp).

Antivirus software is preventing images from loading correctly.
