Macarons all from the same batch in the oven at the same time some burnt and some cracked but some perfect?

I’m just so confused and upset, I make my macarons the same way every time, I’ve literally perfected my recipe, never any broken, hollow, bursted, or burnt. But this rime all three happened spare one tray, first to trays in pic were on the top shelf of the oven exactly how they’re shown in the picture(slightly overlapping) the super burnt ones were. On the bottom, I just don’t know what could have happened I bake my macarons top and bottom all the time, all three is only if I’m a bit rushed but it’s never been an issue for me to set them up like this, it’s not like I’ve only baked them once or twice either, I’ve baked macarons almost every week for over 2 years. I’m just so upset especially because of how full they are. 😔
