Ошибка с Observer при выходе из асинхронной функции только при использовании uvloop в качестве цикла событий ⇐ Python

[Anonymous]

Я не могу понять, почему я получаю сообщение об ошибке при завершении работы при использовании uvloop и не получаю ту же ошибку при использовании без него.
Ошибка: р>
ImportError: sys.meta_path is None, Python is likely shutting down

Мне нужно использовать Observer для просмотра файлов конфигурации и перенастройки поведения. Я получаю ошибку только тогда, когда вызываю Observer.stop() и Observer.join() И использую uvloop. Когда я их не вызываю, в выводе нет исключений. Не имеет значения, вызываю ли я функции stop() и join() из асинхронного кода (см. вариант 1) или из синхронного кода (см. вариант 2 (предпочтительный вариант) )).
if sys.platform != 'win32':
import uvloop
uvloop.install()

async def main(loop_container, connector, processor, observer):

loop_container.set_current_event_loop()

try:
connector.connect_exchange()
asyncio.create_task(processor.process_queue_events())
is_connected = await connector.is_connected()
await connector.start_symbol_watchings()

retry_delay = 1
while True:
await asyncio.sleep(retry_delay) # keepalive
# retry logic (...)

except asyncio.CancelledError:
logging.error(f'{Utils.get_current_datetime()} Execution has been cancelled.')

except Exception as exc:
logging.error(f'Unknown Error: {type(exc).__name__} {str(exc)}')

finally:
await connector.disconnect_exchange()

# Option 1
#observer.stop()
#observer.join()

if __name__ == "__main__":

try:

tick_data_queue = asyncio.Queue()
observer = Observer()
loop_container = EventLoopContainer()

config_abs_path = os.path.abspath(CONFIG_FILE_NAME)
output_abs_path = os.path.abspath(OUTPUT_FILE_NAME)
config_reader = ConfigReader(config_abs_path)
state_persister = StatePersister(output_abs_path, config_reader)

connector = ExchangeConnector(loop_container, tick_data_queue, config_reader, state_persister)
processor = TickProcessor(loop_container, tick_data_queue, config_reader, state_persister, connector)
event_handler = FileChangeHandler(loop_container, config_reader, state_persister, connector, processor)

observer.schedule(
event_handler,
path = os.path.dirname(config_abs_path),
recursive = False,
)
observer.start()

main_coro = main(loop_container, connector, processor, observer)
asyncio.run(main_coro)

# Option 2 (preferred)
#observer.stop()
#observer.join()

except Exception as exc::
logging.critical('Terminated.')

Я не получаю эту ошибку, если:

• Я не использую uvloop
• Я не вызываю ни одну из этих функций

Насколько я понимаю, поток, используемый классом Observer, каким-то образом конфликтует с асинхронный цикл.
Кто-нибудь знает, как решить эту проблему? проблема?
