Error occured "The type initializer for '<Module>' threw an exception." when publishing

Failed to create instance of the V8JsEngine. See the original error message: “The type initializer for '<Module>' threw an exception.”.

        static void configure()
        {
            if (init) return;
            init = true;
            var engineSwitcher = JsEngineSwitcher.Current;
            engineSwitcher.EngineFactories.Add(new V8JsEngineFactory());
            engineSwitcher.DefaultEngineName = V8JsEngine.EngineName;
        }

        public static KoromoScriptInstance CreateNewInstance()
        {
            configure();
            var engine = JsEngineSwitcher.Current.CreateEngine(V8JsEngine.EngineName);

            engine.EmbedHostType("_native", typeof(_Native));

            return new KoromoScriptInstance(engine);
        }

This error occurs when only the project is built with the following command.

my.csproj:
  <ItemGroup Condition="'$(RuntimeIdentifier)' == 'win10-x86'">
    <PackageReference Include="JavaScriptEngineSwitcher.Core" Version="3.3.0" />
    <PackageReference Include="JavaScriptEngineSwitcher.V8" Version="3.3.1" />
    <PackageReference Include="JavaScriptEngineSwitcher.V8.Native.win-x86" Version="3.3.0" />
  </ItemGroup>

command:
dotnet publish -r win10-x86 -c Release /p:PublishSingleFile=true /p:PublishTrimmed=true

It works normally in the case of ChakraCore, but not in the case of V8. It also works fine in Debug and Release mode, not using publish.

Hello!

Is the Microsoft Visual C++ Redistributable for Visual Studio 2019 installed on computer?

Hi! I'm using Visual Studio Enterprise 2019 16.4.3.

After checking a few more, it was found that the /p:PublishTrimmed=true option was the cause of the error. According to Microsoft, using this feature may cause the program to stop working when using reflection features or dynamic loading. So, after removing this option, I was able to fix this problem. Thank you for quick response :)
