Unable to access wp-admin after updating to 2.21.0

Hi,

I updated Limit Login Attempts Reloaded from version 2.20.6 to 2.21.0. After logging in to wp-admin, access to wp-admin is blocked and the following message appears:
Sorry, you are not allowed to access this page.
https://prnt.sc/1295wlc

The plugin was activated for multisite in the network.

In the file limit-login-attempts-reloaded/core/LimitLoginAttempts.php I changed the code from this:

public function __construct() {

	    $this->default_options['gdpr_message'] = __( 'By proceeding you understand and give your consent that your IP address and browser information might be processed by the security plugins installed on this site.', 'limit-login-attempts-reloaded' );

		$this->hooks_init();
        $this->app_init();
	}

to this:

public function __construct() {

	    $this->default_options['gdpr_message'] = 'By proceeding you understand and give your consent that your IP address and browser information might be processed by the security plugins installed on this site.';

		$this->hooks_init();
        $this->app_init();
	}

After this change the wp-admin works fine.

WordPress version: 5.7.1
PHP version: 7.4.16

Can you check why after adding the __() function in the __construct, the wp-admin is not working?

Thanks!
Tomasz
