Reboot your computer again and check if you continue to see the error. If you are using the Windows Store, open it and click on the Download icon to search for and install app updates. Since this error mostly occurs when using a particular app, update that app immediately. Under Windows Update, check for updates and if any, update and reboot your computer once. Press on Windows key+I to open Settings and click on Updates & Security. That can fix quite a few bugs in the system. We will start with updating Windows 10 to the latest version. By the end of this guide, you should be able to work normally without seeing annoying pop-ups. But how? There are a few ways to resolve that error as we will discuss below. If you see this error while using a particular app, then you should begin troubleshooting with that app. If you click Quit, the application will close immediately. If you click Continue, the application will ignore this error and attempt to continue. Some users also see an error that says - Unhandled exception has occurred in your application. The ‘unhandled exception has occurred’ error is not associated with a particular app, which makes it that much harder to resolve.
