Error message "There is an error in XML document (1, 1

Hi  randika118 ,

This error might be related to some corrupted files in the AppData folder.

Here’s a potential fix for this issue:

1.Navigate to the directory on your computer, where is your username.C:\Users\{user}\AppData\Local{user}
2.Find and delete the AppData folder for Power BI (either 64-Bit or 32-Bit, depending on your installation).
3.Relaunch Power BI Desktop.
