The error you’re seeing in Power BI Desktop appears related to a missing or incompatible dependency on the Microsoft Graph library, which Power BI uses for certain connectivity and authorization services. Here are some steps to help resolve this:

 

  1. 1. Repair or Reinstall Power BI Desktop

   - Go to Settings > Apps > Apps & features.

   - Find Power BI Desktop, select it, and choose "Modify" to attempt a repair if available.

   - If repair is not an option or does not resolve the issue, uninstall and reinstall Power BI Desktop from the official [Microsoft Power BI site](https://powerbi.microsoft.com/downloads/).

 

  1. 2. Update .NET Framework

   - Ensure your .NET Framework is up to date, as Power BI relies on it to load dependencies.

   - Download and install the latest version of the .NET Framework from the [Microsoft .NET download page](https://dotnet.microsoft.com/download/dotnet-framework).

 

  1. 3. Clear Power BI Cache

   - Go to the following location on your computer: `C:\Users\[YourUsername]\AppData\Local\Microsoft\Power BI Desktop\`

   - Delete the contents of the Cache folder, which may contain temporary files causing conflicts.

 

  1. 4. Verify Power BI Updates

   - Sometimes new releases of Power BI may contain unpatched bugs. If the October 2024 update introduced this problem, consider rolling back to the previous version if possible, or wait for an upcoming fix.

   - To check for updates or revert, visit the Power BI version archives.

 

  1. 5. Install Microsoft Graph Manually

   - The error indicates that a required Microsoft Graph component (`Microsoft.Graph, Version=4.15.0.0`) could not be found.

   - You can try manually installing the Microsoft Graph package by downloading it through the [NuGet Gallery for Microsoft Graph](https://www.nuget.org/packages/Microsoft.Graph/) if you’re comfortable with it or reach out to your IT support for assistance.

 

  1. 6. Check Power BI Service Status

   - Occasionally, Power BI services may have temporary outages or issues that affect certain functionality. Check the [Power BI Support page](https://powerbi.microsoft.com/support/) for any service interruptions.

 

  1. 7. Contact Power BI Support

   - If these steps don’t resolve the issue, consider contacting Power BI Support with your error details, including the timestamp and session ID, which can help them diagnose the problem.
