The issue has nothing to do with the source code of a theme or plugin or with the configuration of Wordpress. It is:
a 6+ months old bug in File block in Gutenberg that narrows down to
a 4+ years old bug in core Wordpress.
No solution exists for the moment, except for uploading files via Media section of Wordpress Dasboard. As file upload through that way ...

I would suggest first read the wordpress documentation about actions to understand how they work.
Actions are aplit into two section, add_action and do_action
do_action is the "location" where you hook into it.
A basic example of do_action
do_action('my_custom_action');
You can also pass arguments into do_action which can be available in ...

Not automatically.
You don't know a filter exists until something tries to add it or runs it, and you have no guarantee what that filter is for without docs or a human being to describe it.

You could do something like this
add_action('pre_get_posts', 'bt_search_posts');
function bt_search_posts ($query) {
// the posts ids that contain foo bar OR lorem ipsum dolor OR ping pong
$posts_ids = [];
// get the current query vars
$query_vars = $query->query_vars;
// loop each term we want to search and if found, add the post ...

The linked answer was written in 2019, yet the new field guide ("Adding icons in Twenty Twenty") was written about a year later (2020), so you should just use that new field guide, and in response to the main issue:
I am trying to add an icon to the Twenty Twenty-One social icons, but
having trouble registering it.
You're getting the preg_match():...
