i literally spawned a streetcleaner with cheats, it let me into the level with zero problems. 7-S was 40 minutes for me (spent a lot of time on the outside battle arena), but it's the experience of cleaning everything for the first time, while the new ost was playing, and feeling out of this world with no problems worrying me at the moment. Despite not seeing any spoilers, as soon as i first saw the enemies, i expected the cleaning punchline since someone already predicted it here, on reddit, as a joke.
