Not sure what the issue is, when I check the work it says it's incorrect, however when Previewed it runs fine...

When checking work, error message says "Make sure you're giving .star a transform-origin property" but I did this and when Previewed it all runs perfectly and works, yet it says there is an error in the code...

.star-bg {

  transform-origin: 180px 180px;

Jordan's code needs adjusting.

you need to switch the lines (or you get a Bummer! about not using transform-origin):

.star {
  transform-origin: 180px 180px;
  transition: transform .8s ease-out;
}

See Forrest Phillips' reply in this thread (which gave me the clue):

Hi Jordan Parker,

The code challenge never asked to specify an ease-out timing function. If you remove it, you should be good to go. :)
