FYI in case it might: we collect the value that would have been returned by `GetLastError()` in nightly builds and all the crashes in the past six months had that value set to `ERROR_PIPE_NOT_CONNECTED` with the exception of one which had `ERROR_BROKEN_PIPE` (see the "report" tab in [this query](https://crash-stats.mozilla.org/signature/?product=Firefox&release_channel=nightly&signature=mio%3A%3Asys%3A%3Awindows%3A%3Anamed_pipe%3A%3Aread_done&date=%3E%3D2025-04-16T08%3A22%3A00.000Z&date=%3C2025-10-16T08%3A22%3A00.000Z&_columns=date&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=reason&_columns=address&_columns=install_time&_columns=last_error_value&_sort=-date&page=1)). The latter is also the only 32-bit crash we have on file so it's likely the same issue being reported differently by Windows.
