Microsoft.Mashup.Evaluator.Interface.exception: The given key was not present in the dictionary.

I am getting the following error on Power BI and it seems not to be working at all with any query (with simple query like select * from sometable too ). I also tried to reinstall Power BI , removed cache but it was of no use . Kindly help.
