BadImageFormatException

столкнулся с проблемой. Я хотел сделать так, чтобы плагин для сервера отправлял сообщения через Webhook в discord.

Webhook hook = new Webhook("hook")
{
Name = "Сервер",
ProfilePictureUrl = "https://i.imgur.com/YQDOQ5W.png"
};

Подключение к вебхуку "hook" происходит при смерти игрока. Так вот, проблема в том, что при попытке вызвать подключение появляется ошибка BadImageFormatException.

Предполагаю, что ошибка связана с System.Net.Http. Версия проекта 4.5, версия System.Net.Http 4.0.0.0. Помогите, кто может, пожалуйста.
