Thanks for sharing the logs! ComfyUI crashes on startup in comfy-kitchen’s conv3d.py with “NameError: name 'List' is not defined.” H3 Studio then reports a connection error because ComfyUI never starts.
Please stop H3 Studio in Pinokio, run Update, then start it again. The ComfyUI build I checked pins comfy-kitchen 0.2.41, which uses list[int] at that location. If the same error persists, please share the comfy-kitchen version installed in the app’s Python environment and the first traceback from the new ComfyUI startup log. There’s no need to reset the app or re-download your models for this check.
