WAN 2.2 Once saved the video can't delete it from Output folder as it's busy

### 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

Once I run the rendering, everything is fine until I watch the test video. Once I watched in VLC the video and close VLC, I can delete the video file

### Actual Behavior

Once I run the rendering, everything is fine until I watch the test video. Once I watched in VLC the video and close VLC, if I try to delete it gives me the error "The action can't be completed as it's open in Python.".
Once I run another rendering the file is released and I can delete it.
It didn't happen before with Wan 2.1 workflows.


### Steps to Reproduce

Render a Wan 2.2 workflow and once you get the video, watch it and close the media player, then try to delete it.
