Error code: STATE_ERROR.VALIDATION_ERROR.90476

Because your app supports Multitasking on iPad, you need to include the LaunchScreen.storyboard launch storyboard file in your [...] 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: 093a6bf6-76ac-4f28-ab09-a82f76fecd35) (90476)

This thread on developer.apple.com mentions the following:

"I found the answer. The issue was that I was setting Launch screen interface file base name to LaunchScreen.storyboard. The solution was to remove the extension - I only had to provide LaunchScreen"
