NativeLibraryLoader throws exception on .NET 6 Mac Monterey application

[guillemcaldu-popcore]

When trying to build a create a window in a .NET 6 on a Mac Pro M1 with OS Monterey (12.4) the following exception is thrown.

System.TypeInitializationException: The type initializer for 'Veldrid.Sdl2.Sdl2Native' threw an exception.
 ---> System.IO.FileNotFoundException: Could not find or load the native library from any name: [ libsdl2.dylib ]
   at NativeLibraryLoader.LibraryLoader.LoadNativeLibrary(String[] names, PathResolver pathResolver)
   at NativeLibraryLoader.NativeLibrary..ctor(String[] names, LibraryLoader loader, PathResolver pathResolver)
   at NativeLibraryLoader.NativeLibrary..ctor(String[] names)
   at Veldrid.Sdl2.Sdl2Native.LoadSdl2()
   at Veldrid.Sdl2.Sdl2Native..cctor()
   --- End of inner exception stack trace ---

   at Veldrid.Sdl2.Sdl2Window..ctor(String title, Int32 x, Int32 y, Int32 width, Int32 height, SDL_WindowFlags flags, Boolean threadedProcessing)
   at Veldrid.StartupUtilities.VeldridStartup.CreateWindow(WindowCreateInfo& windowCI)
   at Veldrid.StartupUtilities.VeldridStartup.CreateWindow(WindowCreateInfo windowCI)

It's weird because the libsdl2.dylib is there, but it does not seem able to load it. Happens either with x64 or Any CPU.

Did you manage to solve this problem?

working workaround:

brew install sdl2
then add environment variable DYLD_LIBRARY_PATH=/opt/homebrew/lib to .bash_profile or set it inside Run/Debug configuration
