 * Hello,
   I installed your plugin yesterday, and since this morning, my site has
   been encountering 503 errors and is virtually inaccessible.I contacted my hosting
   provider, and they told me the issue stems from your plugin. They provided the
   following details:Repeated calls to the CleanTalk AntiSpam extension (`/wp-json/
   cleantalk-antispam/v1/alt_sessions`).
 * Background processing via `admin-ajax.php`.
 * Repeated database queries:
 * Frequent writes to the `wp_options` table (linked to `action_scheduler_run_queue`)
   and constant `INSERT` operations in the `wp_cleantalk_sessions` table.
   Since 
   I purchased the plugin, I would really like it to work without causing problems.
   For now, I have completely deactivated it without deleting it.For reference:WordPress
   version 7.1.3.PHP version 8.3.
