I had no problem running the program a while ago, but in the past few days it has been running. Does anyone know why Warning: Error occurred while executing the listener callback for event TrainingUpdated defined for class nnet.guis.NNTrainToolModel: Invalid or deleted object. pops up when learning about neural network, it won’t work.

The warning message you're encountering suggests that there is an issue with the MATLAB Neural Network Toolbox GUI or the object that represents the neural network model. This error typically occurs when the object associated with the neural network training process becomes invalid or is deleted during the training process.
