CoPilot is missing, the app is there and it opens completely blank page.

Because Copilot is failing in both the Windows app and Edge, check Microsoft’s service status and wait for the active incident to clear before resetting or reinstalling the app. ^1^

Reports for November 12, 2026 indicate a wider Microsoft outage affecting Copilot and other Microsoft 365 services, with symptoms including blank screens, chats not opening, and servers not responding. ^2^

What to do now

1. Open Microsoft service health status and check for a Copilot or Microsoft 365 incident.
2. If an incident appears, no further PC changes are needed. Check again after Microsoft marks it resolved, then reopen Copilot and refresh the browser.
3. Avoid resetting or uninstalling Copilot during the incident. Since Edge is also unable to open chats or generate responses, reinstalling only the Windows app would not address the browser failure.
4. The hard shutdown has already ruled out a simple temporary Windows session problem, so there is no need to repeat it.

If service health shows normal but both versions still fail

Run Microsoft’s connectivity diagnostic:

1. Open Start, search for Get Help, and launch it.
2. In its search box, enter Copilot connectivity troubleshooter.
3. Run the troubleshooter and apply any recommended remedy. It checks for firewall rules and other connection blockers. ^3^

If multiple personal accounts are involved, open a new InPrivate Edge window and sign in using the same account and sign-in method previously used with Copilot. Microsoft notes that accounts may move to the updated Copilot experience at different times and that chats can take time to migrate. ^4^

If Edge recovers but the Windows app remains white

Only then repair the local app:

1. Go to Start → Settings → Apps → Installed apps.
2. Find Copilot, select … → Advanced options.
3. Select Repair.
4. If Repair does not work, select Reset. Reset can remove locally stored app settings, so ensure any accessible content is synchronized first. ^5^

If it remains blank:

1. Go to Settings → Apps → Installed apps → Copilot → … → Uninstall.
2. Reinstall Microsoft Copilot from Microsoft Store.
3. Sign in with the same account used previously. Microsoft documents uninstalling and reinstalling Copilot as a supported recovery path. ^6^

If both the browser and app still fail after service health returns to normal, report it from Copilot → … → Send feedback → Report a problem and include when it began, the Windows version, and a screenshot. ^4^
