Hi @Abdo_Kamr, have you checked the mentioned error in main.py file?

Hi @Abdo_Kamr Did any of the library updated in between your daily running of rasa model? If so maybe then there could be some dependency conflict.

I’m hoping you have not changed any part of rasa code. I would suggest you uninstall rasa and the yaml library and install a fresh version again.
