Start by reproducing the provided script and trace the model-loading path through bertopic/backend/_utils.py and bertopic/backend/_sentencetransformers.py. Check whether the failure is project-specific or limited to the proxy connection to huggingface.co; done requires a reproducible diagnosis or documented resolution.
