Fatal error in login_form_middle hook

In templates/login-form.php:70 you have this:

apply_filters( 'login_form_middle', '', '' );

This produces a fatal error. The second argument of the filter must be an array, not ''.

The description of the filter in the wp-includes/general-template.php:571, looks as following:

/**
 * Filters content to display in the middle of the login form.
 *
 * The filter evaluates just following the location where the 'login-password'
 * field is displayed.
 *
 * @since 3.0.0
 *
 * @param string $content Content to display. Default empty.
 * @param array $args Array of login form arguments.
 */
$login_form_middle = apply_filters( 'login_form_middle', '', $args );

$args must be an array, not string. As a result, hooks trying to process the filter fail with a fatal error. Here is an example.

public function add_signature( $content, array $args ): string {

Could you please change the line  templates/login-form.php:70 to the following?

apply_filters( 'login_form_middle', '', [] );

Thank you.
