Fixed (account settings manually changed).

You didn't close the * selector, so it grouped it an incorrect thing that was never opened and included pointer-events: none; (below nav::before).

Your code looked like this:

* { ...
nav::before {
    ...
}
z-index: 1000;
pointer-events: none;
}

The correct version is:

* { 
    ...
}

nav::before {
    ...
}
