Why i can't connect to tor using python?

I have an asynchronous parser that works through a tor network:

proxy_auth = str(random.randint(10000, 0x7fffffff)) + ':' + 'foobar'
connector = SocksConnector.from_url('socks5://{}@localhost:9050'.format(proxy_auth))
async with aiohttp.ClientSession(connector=connector) as session:
    for _ in range(5):
        try:
            results = []
            async with session.get(url, allow_redirects=True, timeout=4) as response:
                soup = BS4(await response.text(), 'html.parser')
                results.append(result)

When working there are a lot of errors:

    async with session.get(meta['url'], allow_redirects=True, timeout=7) as response:

Because of this, I cannot parse some web pages. Moreover, after some time of the script workings, another error occurs:

I cannot connect to the tor network, the following is in the tor console:

Jul 21 14:21:38.000 [notice] We'd like to launch a circuit to handle a connection, but we already have 32 general-purpose client circuits pending. Waiting until some finish.

Jul 21 14:27:21.000 [notice] Tried for 121 seconds to get a connection to [scrubbed]:443. Giving up. (waiting for circuit)

What could it be a mistake and how should I be with her? Is it generally possible to use a tor in multiple threads, or is it a stupid idea?
