TypeError in Celery, how can I fix it?

Question

Django

Good day!
Made mailing of letters through Celery. If I run this function through "delay", it gives an error:

TypeError: wrap_socket() got an unexpected keyword argument '_context'

If I run the function just like a regular function, emails are sent without errors...
Here is the function itself:

@shared_task
def send_email(path, context, user_email):  
    msg_html = render_to_string(path, context)
    msg = EmailMessage(
        subject=context['title'], 
        body=msg_html, 
        from_email=settings.EMAIL_HOST_USER, 
        bcc=(user_email,)
    )
    msg.content_subtype = "html"
    msg.send()

    return None

How can I fix it?

PPS This error occurs when sending emails using ssl sending (EMAIL_USE_SSL = True). If you use TLS, then it runs without error
