   Can you give a a similar python code so I can test and compare?

   test_array = np.random.rand(3, 2)
   test_vector = np.random.rand(4)
   np.savez_compressed('/tmp/123', a=test_array, b=test_vector)
   loaded = np.load('/tmp/123.npz')
   print(np.array_equal(test_array, loaded['a']))
   print(np.array_equal(test_vector, loaded['b']))

   This is not a fix but a workaround

           [TestMethod]
           public async Task IssueByMrCOrrupted()
           {
               Dictionary<string, NDarray> arrays = new Dictionary<string, NDarray>();
               arrays["a"] = np.arange(6).reshape(2, 3);
               arrays["b"] = np.arange(3);
   
               var filename = Path.Combine(Path.GetTempPath(), "test.npz");
               np.savez_compressed(filename, null, arrays);
               var archive = np.load(filename);
               Console.WriteLine(archive.repr);
               var a = new NDarray( archive.PyObject["a"]);
               var b = new NDarray( archive.PyObject["b"]);
               Console.WriteLine(a.repr);
               Console.WriteLine(b.repr);
           }
