Asyncio Leveraging OBS Python Script

    asyncio.set_event_loop(_LOOP)

    # Start anything that needs the async loop. The call to run_forever may
    # not be needed, depends on the way the loop dependent components are
    # started.
    _LOOP.run_forever()
    
    # Stop anything that is running on the loop before closing. Most likely
    # using the loop run_until_complete function

        _LOOP.call_soon_threadsafe(lambda l: l.stop(), _LOOP)

    if _THREAD is not None:
        # Wait for 5 seconds, if it doesn't exit just move on not to block
        # OBS main thread. Logging something about the failure to properly exit
        # is advised.
        _THREAD.join(timeout=5)

TypeError: script_load() takes 0 positional arguments but 1 was given

Should work now.
