Unity Linux服务器IL2CPP编译时依赖注入抛出异常

我在Utils脚本中使用以下代码初始化静态变量，每次创建HttpClient时都会调用它：

public static IHttpClientFactory httpClientFactory = new ServiceCollection().AddHttpClient().BuildServiceProvider().GetService<System.Net.Http.IHttpClientFactory>();

我已将所有依赖项（如Microsoft.Extensions.DependencyInjection.dll及其相关依赖DLL）放入Plugins文件夹。使用Mono脚本后端编译时游戏服务器运行正常，但切换为IL2CPP编译时出现以下错误，程序直接终止：

我尝试过在Assets文件夹中添加Link.xml文件来保留相关代码，但错误依然存在，Link.xml内容如下：

<linker>
    <assembly fullname="System.Core">
        <type fullname="System.Linq.Expressions.Interpreter.LightLambda" preserve="all" />
    </assembly>
    <assembly fullname="Plugins/Microsoft.Extensions.Http" preserve="all" />
    <assembly fullname="Plugins/Microsoft.Extensions.Logging.Abstractions" preserve="all" />

    //Plugins文件夹中包含的其他DLL也以同样方式声明...
</linker>
