Rookwoods Trial - can you help with a really annoying rotating arch puzzle?

[AirToob]

This is the one where you can only affect a vital box when looking through a rotating arch, which you can't get through but you can cast a spell through. As is common, the arch has a "red side" and a "blue side".

I finally managed to cast Accio through the rotating arch to bring the box down to ground level, and Wingardium Leviosa to move it to where it is going to be useful.

The last stage is to levitate the box, presumably with ordinary Leviosa, but I can't do that even though I can briefly see the box through the gate in the arch and cast that spell.

The box is now sitting there on the ground in a useful position, and magic is visibly affecting it although it is impervious to spells unless looking at it through the rotating arch.

I have tried jumping off after casting the levitating spell but I'm not quick enough or missing another trick.

Can anyone help me? Until I solve this one I am going nowhere in the game, and I'm certainly not going to restart the trial having got this far!

Edit:

Short version: a video playthrough (see my later post below) shows that the character in the playthrrough can't solve this either, gives up almost immediately and carries on to the next thing.

I've been trying to think which rotating arch and now think I have it. Try going through the arch until the box changes shape and then you should be able to climb it onto the next platform, Sorry if I have the wrong rotating arch

Some items can be brought through the arches, reversing the state that they originally had in each version of the room.

(I'd be a bit surprised if the student hasn't said anything like that, yet. In my current run, I already knew, but the student mentioned it before I could even reach the object I needed to swap into the other version of the room.)

[AirToob]

No, this is some way into the second part, and you CANNOT go through this particular arch, or pull things through it, as it has a kind of impervious grill that stops that. You can cast spells through the grill, though, while the whole thing is rotating (along with yourself if you are standing on the turntable).

I still appreciate the attempts to help - thanks.

If you google it I can almost guarantee you someone has a walk-through for this.

Yes, a Google search usually finds the answer if I'm stuck. In this case, however, the search was quite difficult, throwing up a lot of answers to similar but different questions (rotating arches being all too common). Also, I get the feeling that the current version of the trial is not quite the same as guides written some time ago.

I did find the hint about casting Accio through the arch while rotating with it, buried in a Reddit exchange, but that's only the first part of the puzzle.

I will keep trying myself before doing more searching.

OK, in this walkthrough , about 19 minutes in, our character meets the puzzle I'm stuck in, tries to do it, then simply GIVES UP and goes on to the next thing. At least I did better and got the chest into the right place on the floor, but then couldn't get it permanently raised. Also the chest he pulls down is not quite the same as that in the current game.

Really feels like a bug to me.

As far as I remember, it's just a chest you pull through and loot. It is not vital to the mission.

You are right about it being not vital to the mission, it seems.
But you can't pull it through this particular gate. See the OP and the video (if interested!).

And in the current game, it's not a chest that's lootable. Just a crate whose only purpose is to be jumped on to reach the area above (where there may be a lootable chest to be found).

All in all, a buggy area that is probably best avoided.

I did this yesterday. If you shoot the thing that turns the gate you can see it as a Cube.
Accio the cube, it comes through the gate and becomes a lootable chest, that was it. I expected more but nothing else showed up so I moved on.
