Windows Form Designer fails to load after installing Machina.FFXIV 2.4.0.4 or higher NuGet package in a project in Visual Studio

I apologize if the English is strange as I am using machine translation.

The steps to reproduce are easy.

1. Create a C# "Windows Forms App" project in Visual Studio.
2. Add Machina.FFXIV 2.4.0.4 or higher to your project in NuGet Manager
3. Try to open Form1.cs
4. The "Loading designer..." message does not end and after a few minutes an error message appears: Timed out waiting for the design tools server process to launch to complete.

To narrow down the cause as much as possible, I checked 2.4.0.1 through 2.4.0.4 by building them myself into nupkg. I was able to load the designer up to 2.4.0.3, but 2.4.0.4 failed to load.

You can build and run the Forms App, just can't use the designer.
