Have you tried checking what UWP apps you have installed? If you go to the Microsoft Store and click the three dots on the right and choose "My Library"->"Installed" or "All owned". A lot of them come with Windows 10 but it is possible that an installed one is causing the issue. To uninstall search for the app name in the start menu and right click on it. If it isn't one of the built-in UWP apps like Xbox it should have the uninstall option available.
