The required library hostfxr.dll could not be found. (.NET 5.0 requirement)

[deano019s]

Upon running tool, the following error is encountered:

A fatal error occurred. The required library hostfxr.dll could not be found.

If this is a self-contained application, that library should exist in [C:\Users\local.adm\Desktop\WPCabFilter].
If this is a framework-dependent application, install the runtime in the global location [C:\Program Files\dotnet] or use the DOTNET_ROOT environment variable to specify the runtime location or register the runtime location in [HKLM\SOFTWARE\dotnet\Setup\InstalledVersions\x64\InstallLocation].

The .NET runtime can be found at:

• https://aka.ms/dotnet-core-applaunch?missing_runtime=true&arch=x64&rid=win10-x64&apphost_version=5.0.14

Running on base Win10 22H2 x64 machine. Installing runtime from above does not seem to resolve issue.

Installing .NET Desktop Runtime 5.0.17 and ASP.NET Core 5.0 Runtime seems to resolve, but wondering if the library can exist in the self-contained application.
