How to Fix the Copilot Error: “Sorry, we ran into a problem loading this app” in Windows 11

Below is a list of steps you can take to solve this problem. Start from the top and work your way down, testing Copilot after each one. If it starts working again, don't bother with the other steps.

Check your Internet Connection

Copilot needs an active connection to pull account information and process queries. If your connection is slow, blocked, or unstable, Copilot may fail to load. To check if your connection is working properly, open a web browser and visit several unrelated websites. If pages load slowly or not at all, restart your modem or router. If possible, switch to another network or use a mobile hotspot to test whether the issue is connection-based. Make sure any VPNs or Proxies are disabled as well.

Repair and Reset the Copilot Application

• Press the Windows logo key and the I key to open the Settings window.
• Select Apps, then choose Installed apps.
• Locate the Copilot application in the list.
• Open its settings menu and select Terminate to close any running instance.
• Choose Repair. Wait for the process to finish.
• If the error continues, return to the same settings window and choose Reset. This restores Copilot to its original default configuration.

Sign Out and Sign In to Your Microsoft Account

Sometimes the Microsoft account session becomes invalid or out of sync. To refresh the session, you will need to sign out and then sign back in. You're probably familiar with this from other Microsoft services, tools and software.

You cannot currently sign out directly from Copilot. Instead, open another application such as Microsoft Word or Microsoft Excel. Select your profile picture in the top right corner and choose Sign Out. Once signed out, sign back in with your Microsoft account credentials. Return to Copilot and try again.

Clear the Microsoft Edge Browser Cache

Copilot uses Microsoft Edge for authentication and display functions. If the browser has damaged or outdated stored data, Copilot may fail to load.

To clear browsing data:

• Open Microsoft Edge.
• Select Settings.
• Open Privacy, search, and services.
• Choose Clear browsing data.
• Set the time range to All time.
• Select all available checkboxes.
• Choose Clear now.
• Restart Edge and try Copilot again.
