trainnet not openning the plot's window and get stuck.

I am trying to train a deep neural network to create an OCR. I use the command trainnet. When I execute the command, MATLAB stay busy and do not open the plot's window. It used to work properly, that's it, open the plot's window and you can see how was the network been train. I used to work with MATLAB 2024B and just a couple of weeks ago stop working. I updated to MATLAB 2025A and it is still the same. My guess is that something happended with the interaction of MATLAB with MacOS 15.5. That is the only thing that change.

Someone is having this same problem?

You can check if you have setted trainingOptions with Plots=none. If the training options are correctly setted, maybe the issue is from Graphics Card Driver, you can update your GPU driver from official website.

Thanks for your answer. I left the trainning running all night, by mistake. In the morning the network was trained. It seems that the problem is with the performance of the computer. This network was trained in a matter of seconds before. Now it took hours. I guess it have something to do with the acces to GPUs while processing.
