Copilot app screen is blank followin windows 11 update

Repair the Copilot app first, then reset or reinstall it if necessary; Microsoft has not listed a Copilot blank-screen problem as a known issue for KB5132061/build 26200.9974.^1^

Repair and reset Copilot

1. Close Copilot completely.
2. Open Start > Settings > Apps > Installed apps.
3. Find Copilot, select the … menu, and open Advanced options.
4. Select Terminate if that option appears, then select Repair.
5. Reopen Copilot and check whether its content loads.
6. If it remains blank, return to the same page and select Reset.

Repair attempts to preserve the app’s data; Reset clears its local app data and may require you to sign in again. These are Microsoft’s recommended Windows 11 recovery options for an app that is not running correctly.^2^

Update or reinstall the app

If Reset does not resolve it:

1. Open Microsoft Store > Library > Get updates.
2. Install any available updates for Copilot, Microsoft Store, and related components.
3. Restart Windows and test Copilot.

If the screen is still blank:

1. Open Settings > Apps > Installed apps.
2. Find Copilot, select … > Uninstall.
3. Restart the PC.
4. Open Microsoft Store, search for Microsoft Copilot, and install it again.

Microsoft documents Copilot as a removable app and supports reinstalling it from Microsoft Store.^3^ Store-app guidance likewise recommends updating, repairing/resetting, and then reinstalling the affected app.^4^

If reinstalling does not help

Run the dedicated connectivity check:

1. Open Start, search for Get Help, and launch it.
2. Enter Copilot connectivity troubleshooter.
3. Run the troubleshooter and apply any suggested remedy.

This checks for firewall rules and other connection blockers that can prevent Copilot content from loading.^5^

Also test Copilot in a browser. If the browser version works while the Windows app remains blank, the problem is isolated to the installed app or its Windows profile. If both fail, investigate connectivity, account sign-in, VPN, proxy, or firewall restrictions rather than the app package.

Report an update-correlated failure

If Repair, Reset, reinstall, and the connectivity troubleshooter all fail, report it with diagnostic recording:

1. Press Windows key + F.
2. Select Report a problem.
3. Include KB5132061, OS build 26200.9974, and “Copilot app opens to a blank screen.”
4. Choose Recreate my problem, start recording, open Copilot, wait for the blank screen, and stop recording.
5. Submit the report.

Feedback Hub can attach screenshots and a recording of the reproduction steps, which gives Microsoft the diagnostics needed to investigate a build-specific regression.^6^

Do not uninstall the security update as the first remedy: the published KB notes do not identify Copilot as an affected component, so app recovery and diagnostics are the safer initial path.
