This exception happens when I open the graph tab or the analysis tab while training with a non-default batch size, for 120, it always throws the exception, if 64, it works with a very low chance, for 32, 50% of times works, for 16, it always works and the exception never accuors.

after starting/resuming the training, if I left the preview windows open for a long time, I never face the exception, all menus works fine.
