I've been using Power BI Desktop for more than 6 months now and have created many reports in that period. But, this Tuesday I wanted to open a report I had just created and then I got a "class not registered" error. I also since then was unable to retrieve any report on the desktop and was unable to get close and apply new datasets from power query.
Please how can I get this fixed.
Here's the full error message:
