Inconsistent behavior with standard input

[pbk20191]

I have my simple console echoing script. (python3.12)
If I run this using pycharm's run configuration this works normally echoing the console input back to stdout. However any other running configuration fails. e.g) vscode, python3 my.py ... etc

However, if I use Path('CONIN$').open instead of os.dup any case fails with the same exception.

import asyncio
import sys
from io import TextIOWrapper, FileIO
from typing import TextIO

import winloop
from sys import stdin
import os
from pathlib import Path

async def main():
    loop = asyncio.get_running_loop()
    reader = asyncio.StreamReader(loop=loop)
    
    with FileIO(os.dup(sys.stdin.fileno())) as fileInput:
    # with Path("CONIN$").open() as fileInput:
        transport, protocol = await loop.connect_read_pipe(
            lambda : asyncio.StreamReaderProtocol(stream_reader=reader,loop=loop),
            pipe=fileInput
        )
        try:
            while not reader.at_eof():
                line = (await reader.readline()).decode().rstrip()
                print(line)
        finally:
            transport.close()
if __name__ == '__main__':    
    asyncio.run(main(), debug=True, loop_factory=winloop.new_event_loop)
