How do I time the rewind puzzle to place the key and the block?

I keep hitting a wall in this puzzle platformer where you rewind time for one object but not others. I solved the room by accident once, but now I can't figure out the exact sequence of actions to get the key and the block to their correct spots simultaneously.

I did stumble into a sequence by luck once and tried to lock it in. It felt like you have to set the key on its track, then move the block toward its goal, and only then trigger the rewind so the key stays in place while the block repositions. It never felt rock solid though, like a window that opens and closes with a gust.

I keep thinking the real trick is that the rewind only affects one object at a time, so you have to choose which to fix first and accept the other will drift. I tried letting the key ride on a moving platform and rewinding the block to its spot, but the key moved too after the rewind anyway.

I started wondering if maybe the room is testing patience more than memory. I wandered around and came back with a new idea just to realize the door opened when I least expected it, not when I planned. Could be that the timing window is tiny and you have to observe the lever’s flicker.

Do you think the problem is the order of events isn't consistent across plays?
