Okay I found the issue. ComfyUI is importing the custom node twice because of the extra_model_paths.yaml file. To find that file check this guide.
Can you edit that file by commenting out the custom nodes key?
comfyui_desktop:
is_default: "true"
# Comment this out: custom_nodes: custom_nodes/
download_model_base: models
base_path: /Users/.../Desktop
