Asset validation failed (90476)

I am trying to upload my project to the appple store but am getting this error. If anyone can explain what this error means and guide me through the troubleshooting process it would be greatly appreciated.

"Invalid bundle. Because your app supports Multitasking on iPad, you need to include the LaunchScreen launch storyboard file in your com.ultragroupinc.urmphotouploader bundle. Use UILaunchScreen instead if the app’s MinimumOSVersion is 14 or higher and you prefer to configure the launch screen without storyboards. For details, see: https://developer.apple.com/documentation/bundleresources/information_property_list/uilaunchstoryboardname (ID: b1a8b45f-2285-4a8b-9727-67d5962bf145)"
