I know it's been a while but I just ran into this and for me the fix was adding the following back into my Info.plist. I had inadvertently deleted it.
UIApplicationSceneManifest
UIApplicationSupportsMultipleScenes
UISceneConfigurations
UIWindowSceneSessionRoleApplication
UISceneConfigurationName
Default Configuration
UISceneDelegateClassName
$(PRODUCT_MODULE_NAME).SceneDelegate
UISceneStoryboardFile
Main
