JRE detects an Error at KERNELBASE.dll+0x43b29 during training

So I work at a transfer learning example. My task is to take VGG-16, modify and train it using transfer learning only to predict 2 labels ("Cat" and "Dog"). Here's my code, it is not correctly formatted, so don't get distracted by the "messiness":

    static DataSetIterator trainIter;

    public static void main(String[] args) throws Exception {
        SpringApplication.run(AiProjectDl4jApplication.class, args);

        int seed = 12345;
        int numClasses = 2;


        ZooModel zooModel = VGG16.builder().build();
        ComputationGraph pretrainedNet = (ComputationGraph) zooModel.initPretrained(PretrainedType.IMAGENET);

        FineTuneConfiguration fineTuneConf = new FineTuneConfiguration.Builder()
                .optimizationAlgo(OptimizationAlgorithm.STOCHASTIC_GRADIENT_DESCENT)
                .updater(new Nesterovs(5e-5))
                .seed(seed)
                .build();   


        ComputationGraph vgg16Transfer = new TransferLearning.GraphBuilder(pretrainedNet)
                .fineTuneConfiguration(fineTuneConf)
                .setFeatureExtractor("fc2")
                .removeVertexKeepConnections("predictions")
                .addLayer("predictions",
                        new OutputLayer.Builder(LossFunctions.LossFunction.NEGATIVELOGLIKELIHOOD)
                                .nIn(4096).nOut(numClasses)
                                .weightInit(WeightInit.XAVIER)
                                .activation(Activation.SOFTMAX).build(), "fc2")
                .build();

        TransferLearningHelper transferLearningHelper =
                new TransferLearningHelper(vgg16Transfer, "fc2");

        getImages();
        DataSetPreProcessor preProcessor = new VGG16ImagePreProcessor() ;
        trainIter.setPreProcessor(preProcessor);

        vgg16Transfer.setListeners(new ScoreIterationListener(5));
        log.info("Training starting...");

        for (int i = 0; i < 5; i++) {
            while (trainIter.hasNext()) {
                DataSet currentFeaturized = trainIter.next();
                vgg16Transfer.fit(currentFeaturized);
            }
        }
        log.info("If no results shown -> Summary: Failed");   
    }


    static void getImages() throws IOException {
        Random rng = new Random();
        File parentDir = new File("Path To DataSet"); 

        ParentPathLabelGenerator labelMaker = new ParentPathLabelGenerator();

        ImageRecordReader recordReader = new ImageRecordReader(224,224,3,labelMaker);
        recordReader.initialize(new FileSplit(new File(String.valueOf(parentDir))));

        trainIter = new RecordReaderDataSetIterator(recordReader,150,1,2);

    }
}

The problem lies where I try to train the modified model. I get the results only for the first iteration (that is already pretty high, at 0.9171) and then get this error:

I have already tried to build and train my own network a couple months ago and had the same problem that nobody could really help me with. This time i hope you will. Do you have any idea what could cause it?
