### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Normally install app without bugs.

### Actual Behavior

I made fresh install of ComfyUI on my PC, but had this bug.

To fix it: you just have to go to the ComfyUI folder (for me it was `C:\Users\username\AppData\Roaming\ComfyUI`)
and create the file `extra_models_config.yaml` and type `{}` in it.

### Steps to Reproduce

I opened installer before, reinstalling the app may have caused it.

### Debug Logs

```powershell
-
```

### Other

Fix:
Go to your ComfyUI folder (for me it was `C:\Users\username\AppData\Roaming\ComfyUI`)
Create file `extra_models_config.yaml` and type `{}` into it.
