Hi,
Without being able to directly look at the situation in more depth (the URL to the website would have been great in that respect), it looks like you might have the same problem as here:
www.hikashop.com/support/forum/5-support...s/357244.html#357222
Here is the text of that message in English:
In HikaShop, we have version 5.2.0 of fontawesome which allows you to display icons.
Previously, we loaded this version included in HikaShop, and it was possible to change a hidden option in the database, so as not to load it (in case the template had a more recent version of fontawesome).
As this version is now rather old, on Joomla 4 and Joomla 5, we now ask Joomla to load fontawesome for us with the code:
[coded]
$wa = $doc->getWebAssetManager();
$wa->useStyle('fontawesome');
[/coded]
Locally, on our test sites, when we check the result, it is the file /media/system/css/joomla-fontawesome.css?2865f3 which is loaded by Joomla 5 and the icons are displayed correctly.
On your site, I see that you are also on Joomla 5, but it is the file /media/vendor/fontawesome-free/css/fontawesome.min.css?6.4.2 which is used, instead of the file which is used on our side, despite the fact that you also have this file present (it is just not loaded on your pages).
So, I'm not an expert on fontawesome, but from what I see, the CSS that initializes the font for fontawesome seems to be missing in the file that is used on your site. Below is a capture of the code in the file on our side, which is missing in your fontawesome file:

I'm not sure of anything, but it smells like a problem in the template you are using (or a system plugin) that would load its fontawesome version instead of using the Joomla one, and there will be a problem with it.
Try switching to the default Joomla template to see if you still have the problem. If this is displayed correctly, then you will need to contact support for your template. If this still does not display correctly, then you should see if you have a system plugin related to fontawesome.
Note also that further to this, we got some feedback by someone else that if you're using a template made with Template Creator, it has a setting to fix this:

since Cédric K's Template Creator, there is this function which was in auto mode, but by putting the upload of these fonts in "yes mode" so in forced mode everything works again: it's just happiness!!!! !
