Invoking '/Users/bachi/.local/share/nvim/site/pack/packer/start/copilot.nvim/rplugin/python3/copilot.py:function:CancelCopilotComplete' on channel 5:
Invalid channel: 5
```

Start by reproducing the CursorHold error in the reported Neovim setup, then inspect the plugin's remote request path and the referenced copilot.py CancelCopilotComplete function. Trace why the request reaches an invalid channel and verify that CursorHold no longer raises the error when completion cancellation runs.
