Strangely freezes on team selection (Counter-Strike: Source)

Who faced the problem of freezing when choosing a team? When I go to the server, after a few seconds, everything stops. I can't select a team. I hear chats, I twist the camera. And you can't choose a team, people are all standing. Thirty seconds later, he kicks me from the server with a command like I tayamut. So on all servers.
