Hi @Anonymous ,

Based on my test using Power bi desktop version :  2.76.5678.541 64-bit (December 2019). I cannot reproduce your issue here. Could you please try to re-install it and check again? Or you can ask for help here.

I have reinstalled and it is working now ! Thanks a ton!

Are you trying to open a report by any chance or is this displaying when just opening Power BI Desktop (so not through opening a PBIX file or anything)?

The error states that a parameter could not be null (parametername = collection) which makes me think you are trying to open a faulty PBIX file? (though it should open I guess, even if the param = null)

Kind regards

Thanks for the reply ,

No ,i am not trying to open any file just trying to start desktop and it is showing me this error.

I think because of update ,i have just re-installed  a previous version and working with that ,so problem solved temporarily but it's actually not a solution .
