There is nothing here related to cswinrt, looks like a WinUI issue.

@xperiandri - I updated the following and rebuilt with same error.

<PackageReference Include="Microsoft.ProjectReunion" Version="0.5.0" Condition="$(TargetFramework.StartsWith('net5.0-windows10'))" />
<PackageReference Include="Microsoft.ProjectReunion.Foundation" Version="0.5.0" Condition="$(TargetFramework.StartsWith('net5.0-windows10'))" />
<PackageReference Include="Microsoft.ProjectReunion.WinUI" Version="0.5.0" Condition="$(TargetFramework.StartsWith('net5.0-windows10'))" />
