How is it possible anchor element is not able to press?

Press links in footer is not possible why? https://tikex-dev.com/

I can not replicate this loading code into snippet editor.

Though cursor: pointer is set for each link, the hand icon does not appear when cursor is over <a>.

Even if I remove all the elements and keep only footer, same phenomenon happend. Could position: fixed; has such a side effect?

.footer-parallax {
position: fixed;
bottom: 0;
left: 0;
right: 0;
z-index: -121;
}
