Why aren't language options showing up when I deploy WP on an online server, but they do during local deployment?

WordPress is downloaded from wordpress.org

Why is the language option not displayed when I install WordPress on a live server, but it was displayed when I installed it locally? What causes this issue, and how can I fix it?

This selector will appear when the translation file fails to load. Could this be a permissions issue?

It’s fixed, it really was a permissions issue. Thank you so much!
