Godot 3.5.3. - Tutorial .DLL does not work at all

Godot Version

3.5.3.Stable

Question

I’m using MSYS2 MinGW to compile it, and even if i succeded in making .DLL, i cannot make it run.

I’ve followed all instructions from here: GDNative C++ example — Godot Engine (3.5) documentation in English
All code is taken from there too

I tried this template too: GitHub - rdmsr/godot-gdnative-template: Actually usable GDNative template for Godot and C++
