looking into Mono.TextTemplating.CodeCompilation.RuntimeInfo.GetDotNetCoreSdk(),

static bool DotnetRootIsValid (string root) => !string.IsNullOrEmpty (root) && (File.Exists (Path.Combine (root, "dotnet")) || File.Exists (Path.Combine (root, "dotnet.exe")));

// this should get us something like /usr/local/share/dotnet/shared/Microsoft.NETCore.App/5.0.0
var runtimeDir = Path.GetDirectoryName (typeof (object).Assembly.Location);
var dotnetRoot = Path.GetDirectoryName (Path.GetDirectoryName (Path.GetDirectoryName (runtimeDir)));
if (!DotnetRootIsValid (dotnetRoot)) {
    // this may happen on single file deployments
    return FromError (RuntimeKind.NetCore, "Not a valid .NET Core host");
}

It's clear that runtimeDir is the same as the executable file path on the self-contained version, resulting in dotnetRoot being invalid. This is the debugging output from a self-contained version of TableCraft:

  typeof (object).Assembly.Location
  "D:\\Applications\\TableCraft.Editor.win10-x64\\System.Private.CoreLib.dll"

  var runtimeDir = Path.GetDirectoryName (typeof (object).Assembly.Location)
  "D:\\Applications\\TableCraft.Editor.win10-x64"

  Path.GetDirectoryName (Path.GetDirectoryName (Path.GetDirectoryName (runtimeDir)));
  null
