On a multisite you get a critical error upon activation when on php 8.x
Fatal error: Uncaught Error: Call to a member function add_cap() on null
/plugins/contact-form-cfdb7/contact-form-cfdb-7.php:64 Stack trace: #0
if ( !function_exists( 'populate_roles' ) ) {
require_once( ABSPATH . 'wp-admin/includes/schema.php' );
}
populate_roles();
This fixed the issue when I added it to theme functions.php.
