All Measures and Tables Deleted

I didn't find a solution in the forum so thought this might help others. 


Scenario: I was finalizing a Power BI Desktop report and while a report was rendering, an Unknown Error message appeared.  All visualizations went blank with message "Something's wrong with one or more fields. See Details"  I had made no changes but all reports were showing this error.  I reported this through the send a frown option and it was said to be known.  The last time I backed up the report was a week earlier so I had lost many hours of work. (lesson learned)  I eventually noticed the Date table was gone as were any measures or columns I had added using Power BI.  I have no idea how they disappeared or how I could recover these without a recent backup.   


Solution:  I found the most recent temp file and was able to restore a lot of my progress.  The files are located at

\users\user\AppData\Local\Microsoft\Power BI Desktop\TempSaves
