Error Code: D2E8DA72
This document has no version number.
My situtation: Developed a Tableau dashboard spending lots of time using Tableau Public and when I tried to publish, it crashed and closed automatically without showing any prompts.
Steps taken:
Searched my computer and found Temp app created at ..\Users\AppData\Local\Temp\TableauTemp
When I tried to open that app I was prompted with above Error dialog. It was trying to open in Tableau desktop (not Public)
Then I tried with Tableau public desktop that didn’t work either but error message was different.
Resolution:
Then I took a copy of that Temp TWB in a different location and extracted it using 7-zip extractor.
A file (TWB) and a folder (Data) got extracted, twb file had the same name which I used initially.
Then I was able to open up the extracted TWB file with Tableau desktop (not Public). After opening I saved that file as packaged workbook and tried opening packaged workbook with Tableau Public desktop, this time it worked perfect.
Tableau Desktop/ Public Desktop Version: 2021.1.2
