Direct Query - Collection was modified; enumeration operation may not execute

Continuously run into this error with a data model built using Direct Query to a SQL on-premises database.  This occurs after saving pbix file and opening the next day.  I have had to try converting to zip and replacing the guts of a blank pbix with that of the "broken" direct query pbix but was unsuccessful with the last two.  I am now having to restore a backup from onedrive and lose any changes made since.

Feedback Type:
Frown (Error)

Hi @PowerDAX,

 

To be honest, I would suggest you file a support ticket here for such errors. But you still can try to upgrade the Desktop first.
