 **Steps to reproduce**
 1. Add a custom user role, and pass null to the capabilities argument.
 e.g.
 {{{#!php
 <?php
 function add_custom_role_without_capabilities() {
         add_role( 'ola', 'Ola', null );
 }
 add_action( 'init', 'add_custom_role_without_capabilities' );
 }}}
 2. Now, call the get_users function with 'capability' args. e.g.
 {{{#!php
 <?php
 $users = get_users( [
         'capability' => [ 'edit_posts' ],
 ] );
 }}}

 You should see a fatal error.
