Authoring generator throws Win32Exception for methods with WindowId parameters

[Sergio0694]

Describe the bug

Just noticed the following failure when using WindowId as a parameter for a method:

"CSC : warning CS8785: Generator 'SourceGenerator' failed to generate source. It will not contribute to the output and compilation errors may occur as a result. Exception was of type 'Win32Exception' with message 'Incorrect function'."

To Reproduce

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net8.0-windows10.0.22621.0</TargetFramework>
    <Platforms>x64;ARM64</Platforms>
    <CsWinRTComponent>true</CsWinRTComponent>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Windows.CsWinRT" Version="2.0.4" />
  </ItemGroup>
</Project>

using Windows.UI;

namespace MinimalWinRTComponentTest;

public sealed partial class MyClass
{
    public void Test(WindowId id)
    {
    }
}

Expected behavior

Should work fine..?
