Font Awesome (6.4.0) not working for [light, doutone and thin] => HELP { ASAP }

Question

This pile of code:
<i class="fa-thin fa-arrow-up-right"></i>
& this:
<i class="fa-light fa-arrow-up-right"></i>

Doesn’t work, even if it works it shows Stack of Line or GitHub Logo but in italic style.
I already added a gtag and a bootstrap cdn, font awesome kit (and CDN). All in latest version.

Answer 1

https://fontawesome.com/search?q=arrows&o=r&s=light

I went searching here and it's a pro version icon. Does that explain anything to you?

Answer 2

The italics are because of the italics tag <i></i>, you could change them to another inline element.

Answer 3

Use the old version, maybe 6.1.2 the new version needs pro to do most of the job

Answer 4

I don’t think i can change it, the <i></i> tag is the tag should and will only be use when using Font Awesome Icons. I’m talking about the “Thin” and the “Light” in ‘fa-thin’ and ‘fa-light’ that it doesn’t work. Thanks.

Answer 5

I’m sorry, but i don’t think you understand. See what i need to know is => “Why does the THIN and LIGHT mode is not working in Font Awesome”
