Hi @PruthviBalaji 

You mentioned that you got an error when you opened the report , you opened it in Service or in Desktop ? If in the Service , can you open the other report ? If in the Desktop , what is your Desktop version ? Did you update your Desktop recently ? 

If the error is caused by updating to the August Desktop, you can download the latest installer from Download center, uninstall the previous version and reinstall the update.

Download Microsoft Power BI Desktop from Official Microsoft Download Center
