When integrating bbPress and WordPress and using only the WordPress registration, no default role was assigned to the user in bbPress. This will give the user a role of member in bbPress. Just activate, and whenever a user signs up, they will automatically have the bbPress role assigned. Note: this is not retroactive; it is only for new registrations.

Add bbPress Default Role

Automatically give WordPress users a bbPress role of member when registering.

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.

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
