This plugin restricts access for Authors and Contributors so they can only see their own Media Library uploads.
This has two main uses: Make it easier for Authors to locate their own uploads when Media Libraries grow very big and prevent Authors from using or downloading media that belongs to other users.
Admins and Editors will still be able to see everyone’s uploads.

Restrict Media Library Access

This plugin works fine in WP 5.7.1 

It's just the example code from the official WP docs for the ajax_query_attachments_args filter, with a line added to check if the current user is an administrator. It's very simple.

There's no reason this plugin shouldn't work in an up-to-date WP installation

Control what menu items your site’s visitors see, with visibility rules. Here are a few examples:
<ul>
<li>Display a menu item only if <code>User is logged in</code></li>
<li>Hide menus if <code>Device is mobile</code></li>
<li>Display menus only for <code>Admins and Editors</code></li>
<li>Hide Login or Register links for <code>Logged in Users</code></li>
<li>Display menus for <code>Users from US or UK</code></li>
<li>Display menus only for <code>Customers with active membership</code></li>
<li>Display menus for visitors browsing with <code>Language English or Spanish</code></li>
</ul>
After the plugin is enabled, each menu item will have a new option “Change menu item visibility” which will enable the selection of visibility rules.
