OneTrainer: Problem with updated version and the config + train.bat you provided.

I've been using the OneTrainer config and train.bat that mal provided for training Z-Image Turbo loras and it's been great. No issues. Earlier today I updated OneTrainer in any attempt to try training Z-Image base loras and now the config doesn't work at all. The command window throws up the error below then sits there doing nothing. This is above what I know so any help in sorting this would be great appreciated.

Error:

UPDATE: I found some different configs on mal's HF page and tried again, letting it run in the background. It appears to have started training for Z-Image base. So hold on before replying and let's see how it goes.
Definitely took longer to start than before the update.
