object NoneType can't be used in 'await' expression

### 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)

### Your question

Updated the last version of ComfyUI, now when I try start ComfyUI I get this error before opening the webpage.
