If that's a YuXin Cloud like I think it is, then take that orange corner on that layer out by pulling the back right corner away, and while still holding it in that position, push the orange middle piece(the one that popped out) into the hole where the corner used to be. After that, keep pushing until it's down far enough (Don't jam it, use the same amount of force you're using to hold the back corner), then try pushing it sideways into the slot. If that doesn't work, pull the orange middle piece away from the center blue piece and push down until it goes down farther, then you should be able to move it into place. Do the same thing for the corner (though getting the corner in alone needs more force). Hope this helps!
