querySelectorAll selects an array of elements—in this case, an array of all of the <li>s—so you need to get the first element that comes out of querySelectorAll. Also, removeChild removes a child from its parent, so you need to call removeChild on myList with the argument firstListItem.

let myList =  document.querySelector("ul");
let firstListItem = document.querySelectorAll('li')[0];
myList.removeChild(firstListItem);
