asyncio.create_subprocess_exec() will throw notImplementedError exception on Windows

[Unintendedz]

Thanks for the excellent plugin

here is my code for the test

import asyncio


async def main():
    await asyncio.create_subprocess_exec('C:/Windows/System32/cmd.exe')


if __name__ == '__main__':
    asyncio.run(main())

workaround:

import asyncio


async def main():
    await asyncio.create_subprocess_exec('C:/Windows/System32/cmd.exe')


if __name__ == '__main__':
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
    asyncio.run(main())
