Hi all,

Have never had such a stupid issue in my entire life.

Have copied the issue details below but pretty much i started getting this error which doesnt mean anything.

It happens when I attempt to open or save a report. It does successfully save/refresh etc but it wont publish.

I have updated to the latest version, uninstalled and reinstalled entirely and still getting the error.

It even happens when opening a blank report or opening the app for the first time.

Details below.

@moseshewetson ,

Do you also get this issue in old version of Power BI Desktop? What is your data source?

There is a similar thread discussing similar issue, which is solved by unchecking "Autodetect new relationships after data is loaded" in Power BI Desktop, please check if this workaround works for you.

Regards,
Lydia
