Hi @Mehmoodul1994,

Since I’m not able to reproduce the issue, in your scenario, to determine whether this issue is related to pbix file itself, please create a new report and re-open it with the update version Power BI desktop for a test. 

As I know, the most probability caused this error might be that your pbix file has been destroyed. You can recover a version of your file by going to File > Options > Auto Recovery, opening that location and searching for an auto-recovered version of the pbix.

Thanks,
Yuliana Gu
