Every scheduled refresh has failed because of a new RetrievePrivilegeForUser error

Hello, 

I've got a dozen reports that automatically refresh every morning at 8 AM. Today they all failed (and still fail when manually refreshed) because of a RetrievePrivilegeForUser error that I've never seen before. For the past year they have all been refreshing without a problem. Here is an example error; the only variable in these errors is the name of the privilege, which is based off of the name of the Dataverse table the report uses.

OK, this has been resolved -- it's almost as simple as it sounds. It turns out all my privileges mysteriously disappeared from the Power Platform Admin Center overnight, but after reinstating them, we are back in business. The reports now refresh successfully.
