Fortunately, there are several simple solutions to resolve this issue. In this article, we will guide you through step-by-step instructions to fix the problem effectively.

Each solution is explained in a clear and basic way to help even beginners understand and apply the fixes. Let’s get started and get your Power BI working smoothly again.

Follow these steps carefully, and you will likely solve the error without much hassle.

Quick Note: Preliminary Checks Before Troubleshooting

  • Make sure your Windows 11 system is up to date. Some Power BI errors happen due to outdated system files.
  • Ensure you have a stable internet connection, especially if your data sources are online.
  • Confirm that your Power BI Desktop version is the latest. Older versions may have bugs causing this error.
  • Check if the data source you are trying to access is available and you have permission to access it.

Step 1: Restart Power BI and Your Computer

Sometimes, the simplest solution works best. Restarting Power BI Desktop can clear temporary glitches that cause loading errors. If that doesn’t help, try restarting your computer.

This step is important because it refreshes system resources and resets any temporary conflicts.

Step 2: Clear Power BI Cache

Power BI stores cache data to speed up performance, but corrupted cache files can cause errors. Clearing the cache can fix this issue.

  1. Close Power BI Desktop completely.
  2. Press Win + R to open the Run dialog box.
  3. Type %localappdata%MicrosoftPower BI DesktopAnalysisServicesWorkspaces and press Enter.
  4. Delete all folders inside this directory. These contain cached files.
  5. Reopen Power BI and try loading your table again.

Clearing the cache forces Power BI to fetch fresh data, eliminating errors from corrupted cache files.

Step 3: Check and Update Data Source Credentials

Invalid or expired credentials can block Power BI from loading tables. To check and update them:

  1. Open Power BI Desktop.
  2. Go to File > Options and Settings > Data Source Settings.
  3. Select the data source causing the issue and click Edit Permissions.
  4. Click Edit under Credentials and re-enter your login details.
  5. Click Save and try loading the table again.

Updating credentials ensures Power BI can properly connect to your data source without authentication errors.

Step 4: Repair Power BI Desktop Installation

If the error persists, your Power BI installation may be corrupted. Repairing it can restore missing or damaged files.

  1. Press Win + I to open Settings.
  2. Go to Apps > Installed apps (or Apps > Apps & features).
  3. Find Microsoft Power BI Desktop in the list.
  4. Click the three dots next to it and select Modify or Repair (depending on the option available).
  5. Follow the on-screen instructions to complete the repair.
  6. Restart your PC and check if the issue is resolved.

This process fixes common installation issues without needing to uninstall and reinstall the entire program.

Step 5: Update or Reinstall Power BI Desktop

Running an outdated version may cause compatibility problems on Windows 11. To update or reinstall:

  • Visit the official Power BI Desktop download page.
  • Download the latest version.
  • If you already have Power BI installed, uninstall it first via Settings > Apps.
  • Install the new version and restart your computer.
  • Try loading the table again.

Keeping your software up to date ensures you benefit from bug fixes and improved compatibility.

Alternative Advanced Solutions

Check Privacy Settings in Power BI

Incorrect privacy settings can prevent data loading. To adjust:

  1. Open Power BI Desktop.
  2. Go to File > Options and Settings > Options.
  3. Under Current File, select Privacy.
  4. Choose Ignore Privacy Levels temporarily and click OK.
  5. Try loading the table again.

Remember to reset privacy settings after testing for security reasons.

Check Firewall and Antivirus Settings

Sometimes, security software blocks Power BI from accessing data sources. Make sure to:

  • Allow Power BI Desktop through Windows Firewall.
  • Add Power BI as an exception in your antivirus software.
  • Temporarily disable firewall or antivirus to test if they are causing the issue.

Always re-enable security software after testing to protect your system.
