Start with Amazon.Lambda.TestTool/Commands/RunCommand.cs at line 45 and reproduce the reported `dotnet lambda-test-tool start` invocation on Windows. Trace how the start command validates emulator options and determine the intended behavior for an invocation without them. Done means the command handles this case according to that behavior rather than producing an unhandled exception.
