The "Create" button in Looker Studio is not working.

The non-functional buttons are located in the upper left corner of both the Reports tab and Data Sources tab.

The "Blank Report" button and the center button on the Reports tab are working correctly.

Once one or more reports or data sources are added, this button disappears, making it impossible to add new data sources.
