The error originates in color-buffer.coffee line 166, where a task termination fails with a kill EPERM on Windows. Start by examining the task termination logic in that file and the Atom Task API. Reproduce the issue on Windows to understand the process lifecycle. Check if the child process is already dead or if permissions are insufficient.
