Has anybody had the issue where all dataflows in a workspace have stopped working (but dataflows in all other workspaces on the capacity are fine)? We are on Power BI Premium Gen 2. Connecting to the dataflows in Power BI Desktop produces a "Dataflow Internal Error" error message and datasets fails to refresh with a similar error. Dataflows cannot be opened in the service ("Something went wrong - There was a problem opening your dataflow") and all dataflow refreshes fail ("There was a problem refreshing your dataflow"). New dataflows cannot be saved.
I logged this as a critical issue with support first thing on 03/02/22 but despite having had a call to show the issue have not had anything useful back yet. We depend on dataflows heavily and it is very concerning that all dataflows in an entire workspace can be wiped out like this without a speedy resolution.
