Can't open DXF files

I’ve tried loading multiple DXF files and always get errors. Here is my code:

Console.WriteLine("Setting license");
		Aspose.ThreeD.License license = new Aspose.ThreeD.License();
		license.SetLicense("Aspose.3D.lic");

		System.Reflection.Assembly asm = System.Reflection.Assembly.GetAssembly(typeof(Aspose.ThreeD.Scene));
		Console.WriteLine("Aspose.3d Version: " + asm.FullName);

		asm = System.Reflection.Assembly.GetAssembly(typeof(System.Int32));
		Console.WriteLine(".Net Core Version: " + asm.FullName);


		try
		{
			string fileName = "Animals39.dxf";
			Console.WriteLine("Reading " + fileName);
			var scene = new Scene(fileName);
			Console.WriteLine("Done!");
		}
		catch (Exception ex)
		{
			Console.WriteLine(ex.ToString());
		}

and here is the output:

I’ve tried 5 different dxf files from various sources, all of which open fine in multiple DXF viewers. Here is a link to one which causes the problem:
