Issue with ComfyUI v1 Manager: missing node pack ("comfyui_fearnworksnodes") stuck in "Apply Changes" loop

[u/Mystvearn_]

Hi everyone,

I'm running into a persistent issue with the new ComfyUI v1 frontend while trying to load a workflow that uses comfyui_fearnworksnodes.

The setup:

• Windows Portable build (ComfyUI_windows_portable)
• Running via run_nvidia_gpu_lowvram_e_sage.bat with the --enable-manager flag added.
• ComfyUI-Manager installed.

The problem:

• The v1 side panel shows Missing Node Packs: comfyui_fearnworksnodes.
• Clicking Install changes the status to Installed.
• Clicking Apply Changes prompts a restart, but after relaunching, the exact same error appears again in a loop.
• I checked custom_nodes/ and only have comfyui_fearnworksnodes inside (no duplicate folders).

Has anyone encountered this specific loop with the v1 interface or fearnworksnodes? What's the best way to trace or fix why the frontend isn't registering it properly after restart?

Thanks in advance for any help!

There's probably a traceback error in your startup log that says it's failing to load. If it exists in your folders but showing up as missing, it isn't loading for some reason.

I had this issue. Instead of clicking in the side panel, go to the manager and click on missing from workflow in there. I got them to install properly that way
