ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

Nobody has claimed this yet.

I'm on 14900HX 32GB RAM and RTX 4080. (Acer Helios 18)

Am getting following error while generation in progress.

The traceback points to asyncio/events.py and asyncio/proactor_events.py during generation, after decoding and model movement. Start by reproducing the generation failure on Windows and tracing the connection lifecycle around that callback. Done requires identifying which connection is being closed and documenting a project-specific reproduction or confirmed fix.
