Open your Package.appxmanifest file from your main project and add a:Optional="true"
to
<uap:SplashScreen Image="AssetsSplashScreen.png" a:Optional="true" xmlns:a="http://schemas.microsoft.com/appx/manifest/uap/windows10/5" />
However, you will still need to provide a splash image because a:Optional
Specifies whether an app should be launched without a splash screen.
If true, the splash screen will not be shown if the app can launch
fast enough. If there is a delay in the app launch time, the splash
screen will be shown. If false, the splash screen will always be
shown.
