Please don't post images of code, instead edit your question to include your code (an minimal reproducible example) as well as any input and desired output along any error messages you may or may not be getting – MindSwipe

If you look at the docs for the InputInjector.TryCreate() method, it says:

Note: The APIs in this namespace require the inputInjectionBrokered restricted capability.

You need to update your Package.appxmanifest to add the capability, for example:

<?xml version="1.0" encoding="utf-8"?>
<Package
    ...
    xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"
    IgnorableNamespaces="... rescap">
...
<Capabilities>
    <rescap:Capability Name="inputInjectionBrokered"/>
</Capabilities>
</Package>
