Attempting to refresh a .pbix file with connection to a local MS Excel file, that previously always refreshed just fine, now results in the following error:

OLE DB or ODBC error. A connection could not be made to the data source with the Name of 'd6466813-2bfb-...'

Could this have been caused by a recent Power BI Desktop update? If not, does anyone have a solution to this problem? I've tried creating a new .pbix file with a connection to a simple .xlsx or .csv and get the same error each time.

Downgrading from Feb 2020 version to Dec 2019 version solved the issue
