@dosubot[bot] commented on GitHub (Sep 30, 2025):

When custom nodes become unrecognized after updating Comfy Desktop, it's often due to a mismatch between the location of your custom nodes and the configuration file that tells ComfyUI where to find them. In v0.4.74, the app relies on the extra_models_config.yaml file—specifically the desktop_extensions.custom_nodes entry—to locate custom nodes on disk. If this config is missing or points to the wrong directory, nodes won't load, even if you revert versions source.

Here’s what you can do:

Check that your custom nodes are present in the expected directory (usually ComfyUI/custom_nodes).
Open the extra_models_config.yaml file in your user data directory and verify that the desktop_extensions.custom_nodes path matches the actual location of your custom nodes.
If the config is missing or incorrect, manually update it or regenerate it using ComfyUI Manager or by reinstalling the app source.
Make sure all dependencies for your custom nodes are installed in ComfyUI’s Python environment. Use ComfyUI Manager for this, or run pip install -r requirements.txt for each node source.
Restart ComfyUI after making changes.

If you still see missing nodes, try disabling all custom nodes from the settings menu, then re-enable them one by one to isolate any problematic node source.

Let me know if you need help with any of these steps!

@manassm I'm very sorry to hear that! Did you happen to notice anything that seemed strange or out of place during the update?

I haven't recognized anything particularly different than previous updates.
It's working fine after reinstalling the nodes.
Thank you for your interest.
