asyncio.create_subprocess_exec return NotImplementedError when use flag --reload in Windows

[axiangcoding]

This is an issue that was identified early on and has been answered at (https://stackoverflow.com/questions/70568070/running-an-asyncio-subprocess-in-fastapi-results-in-notimplementederror).

After referring to the answer, I removed --roload, and everything worked.
I understand its not a issue when the code move to the production, but it's really inconvenient.
So I'm asking if there is a best practice for keeping the --reload and making sure asyncio.create_subprocess_exec is working properly in Windows?
