Webcam Capture node error.

### 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

Webcam Capture should capture an image at run time.

### Actual Behavior

Hitting Run results in this error.

```

### Steps to Reproduce

Webcam Capture > Preview Image, then Run

### Other

_No response_

Start with comfy_extras/nodes_webcam.py and trace its call into folder_paths.py:get_annotated_filepath, then review nodes.py:load_image. Reproduce the Webcam Capture > Preview Image workflow on Windows using the reported error, and verify that Run successfully loads the captured image without the invalid-path exception.
