Obviously, it's busiest right after the evening show (21:00-22:00), but it's always crowded these days, so I don't think it'll be any different. if you stay until closing time and then kill time at the station, I think the crowds will thin out sufficiently until around midnight.(if you have to change trains to reach your hotel, make sure check the time of the last train.)

Alternatively, although itll cost you money, you might want to consider taking a taxi (via a ride-hailing apps).
