Hello! I'm Jen, and I'd be happy to help you out with this issue.
I'm sorry to hear you're experiencing this issue with the Copilot app. Have you tried restarting your computer then try using Copilot again to see if the error disappears? Also, please ensure Windows is updated to the latest version. Go into Settings > Windows Update > Check for Updates and install available updates.
If the problem still persists, you can try repairing the Copilot app and check if it helps. Go into Settings again > Apps > Apps & features > Scroll down and look for Copilot app > Click on three dots and select Advanced options > click Repair then check if the problem is resolved. You can also try resetting the app. Do the same steps, under Advanced options, click Reset then verify the result. Let me know how it goes. Thank you.
I hope this information helps. If you have any questions, please let me know and I'll be glad to assist you further.
Best Regards!
Jen :)
