Cannot load animate template

### Custom Node Testing

- [ ] 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

I have installed ComfyUI and deployed all the custom nodes. I can load the templates normally. But there is a specific template which I could not load in my UI interface.

I have tried all ways, installed new envs, but failed. There is no error, no message, no change after open the json file. The file is mentioned as [here](https://github.com/Comfy-Org/workflow_templates/blob/main/templates/video_wan2_2_14B_animate.json)

Expected was to open template, than I would have provided image and sample mp4 video to animate the image according to video, and of the same length as of video.

### Actual Behavior

When I open the file, nothing happens.

### Steps to Reproduce

Installed ComfyUI, installed custom nodes required for animate template.
Started the ComfyUI server.
Opened browser (tried firefox, Chrome) both but same response
opened the template [file](https://github.com/Comfy-Org/workflow_templates/blob/main/templates/video_wan2_2_14B_animate.json)

Nothing happens
