go to SM packages, 3dot menu for ComfyUI > Python Packages > click the + button and paste in after the "pip install":

torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu128 --force-reinstall

---

The change to cu130 PyTorch builds is causing a problem, likely an underlying compatibility conflict

It works now and thanks for your advice.
