asyncio import issues - no attribute 'StreamReader'

I have had asyncio and websockets work fine several times, but for some reason it sometimes refuses to run and will refuse to ever run again. I have had this happen across multiple devices, with code as simple as just imports:

import asyncio
import json
import websockets

Interestingly, when using Pydroid3 on Android, any code I write with asyncio works fine, but only until I save it to a file. Once it's been saved, it stops working. I can copy all the text and paste it to a new, unsaved file and it again works fine until saved. This awful solution does not work for Windows, unfortunately. I am using Python 3.9.0 for Windows. The stacktrace produced by running the code shown above is as follows:

Traceback (most recent call last):
  File "C:\Users\user\Documents\AtomTests\socket.py", line 1, in <module>
    import asyncio
  File "C:\Users\user\AppData\Local\Programs\Python\Python39\lib\asyncio\__init__.py", line 8, in <module>

    async def read_request(stream: asyncio.StreamReader) -> Tuple[str, "Headers"]:
AttributeError: partially initialized module 'asyncio' has no attribute 'StreamReader' (most likely due to a circular import)
[Finished in 0.158s]

I've searched a bit for this error, but either it's uncommon or I'm just blind, because I couldn't find anything. Has anyone else had this happen to them?

Your local socket.py file is shadowing Python’s socket module. Rename your file and your imports will work.
