Sign- in Power BI desktop

Hi rajkumar711 ,

Thanks for reaching out to the Microsoft fabric community forum. Also thank you pbiuseruk for the guidance. You do need to sign in with a work or school account, and ensuring that you’re on the latest version of Power BI Desktop is important.

In addition to that, please also verify the following:

• Delete the User.zip and Cache folders located at: C:\Users\<YourUser>\AppData\Local\Microsoft\Power BI Desktop.
• Check your firewall or proxy allows access to login.microsoftonline.com and app.powerbi.com. Temporarily disable VPN if active.

• Confirm that Microsoft Edge WebView2 Runtime is installed, as Power BI Desktop uses it for authentication.

• Log in at https://app.powerbi.com to verify your account works, then retry in Power BI Desktop.

These additional checks usually resolve blank sign-in screen behavior. Please feel free to reach out for any further questions.

Thank you .
