Saving a Simulink model programmatically inside the closeFcn callback (like using save_system(gcs)) can cause issues because the model is already in the process of closing, and certain resources or states may not be available or stable at that moment. This can lead to model corruption, especially for complex blocks like Stateflow charts.
Here are the alternate solutions that you can try:
- Avoid saving in closeFcn: Instead, try saving your model before closing it, such as in a custom button, script, or using the PreCloseFcn callback if available.
- Manual Save: Save changes manually before closing, or use autosave features. Kindly go through https://www.mathworks.com/help/simulink/slref/save_system.html to know more.
- Alternative Callbacks: Consider using other callbacks like PreSaveFcn or PostSaveFcn for custom actions related to saving. Kindly go through https://www.mathworks.com/help/simulink/ug/model-callbacks.html to know more.
