Datamart stuck on "Power query processing"

[elaine_dunwoody]

I'm transforming data in the datamart and when I click save, it gets stuck in the "Power query processing" stage for a long time. Then after a while, the "Return to editing" button becomes clickable. If I click on it, I lose my changes, but it doesn't show any error messages. I don't know what failed.
