Why is my C# code not finding the dll gstreamer-1.0.dll?

This is my .csproj:

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
   <TargetFramework>net6.0</TargetFramework>
   <ImplicitUsings>enable</ImplicitUsings>
   <Nullable>enable</Nullable>
 </PropertyGroup>

 <ItemGroup>
   <PackageReference Include="gstreamer-sharp-netcore" Version="0.0.8" />
 </ItemGroup>

When I run my C# script:

var rtspsrc = ElementFactory.Make("rtspsrc", "source");
var rtph264depay = ElementFactory.Make("rtph264depay", "depay");
var h264parse = ElementFactory.Make("h264parse", "parser");
var mpegtsmux = ElementFactory.Make("mpegtsmux", "muxer");
var hlssink = ElementFactory.Make("hlssink", "sink");

// Elements Config
rtspsrc["location"] = rtspUrl;
rtspsrc["latency"] = 200;
hlssink["location"] = $"{directoryPath}\\%06d.ts";
hlssink["target-duration"] = 5;
hlssink["playlist-location"] = hlsOutputPath;

// Pipeline Creation
var pipeline = new Pipeline("hls-pipeline");

// Linking
rtspsrc.Link(rtph264depay);
rtph264depay.Link(h264parse);
h264parse.Link(mpegtsmux);
mpegtsmux.Link(hlssink);

// Add to pipe
pipeline.Add(rtspsrc, rtph264depay, h264parse, mpegtsmux, hlssink);

// start pipe
var ret = pipeline.SetState(State.Playing);

if (ret == StateChangeReturn.Failure)
{
    Console.WriteLine("Unable to set the pipeline to the playing state.");
    return;
}

// Main Loop
GLib.MainLoop mainLoop = new GLib.MainLoop();
mainLoop.Run();

// dispose...
pipeline.SetState(State.Null);

I get this error on the console:

Error: Unable to load DLL 'gstreamer-1.0-0.dll' or one of its dependencies: Não foi possível encontrar o módulo especificado. (0x8007007E)

I'm using

The error occurs when this line is called:

var rtspsrc = ElementFactory.Make("rtspsrc", "source");

The first line that uses the Gstreamer sharp library.

The .dll is in a folder that was created when I installed Gstreamer on my machine, I put the paths in the environment variables so that GSTREAMER could use

Screen Capture of Enviroment Variables

What didn't make sense is that when I run something like this:

var pipeline = Parse.Launch("playbin uri=http://download.blender.org/durian/trailer/sintel_trailer-1080p.mp4");"

it works...

I have already configured the GStreamer ENVIRONMENT PATH paths. I'am a really newbie so could someone explain it to me?

I need GSTREAMER to generate the .ts and .m3u8 files. But it's causing that DLL error.
