It has already worked fine for me but I run it today and now I get this error that I can't identify. can you help me?

Although I am not entirely sure, I think you are loading in a model trained on a previous version of BERTopic (<v0.12) and tried to load it in with a current version (=v0.12). Since the API can change between releases, I would advise making sure that the environment you work in is kept the same between saving and loading the model. In other words, if you saved the model with v0.10, make sure to load it in with the same version.
