When installing the Translation plugin through Manager, an error occurs. After deleting the Translation plugin, it can be opened

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
