   any other plugins) as well.

 * The error message you are encountering indicates a compatibility issue, most 
   likely due to the PHP version you are using.
 * Check if you’re using a PHP version recommended by WordPress and change it if
   you are not.
    You can experiment with PHP versions 7 and 8 to see which one solves
   the problem.

 * I’ve try with different PHP versions (7.4,8.0,8.1,8.2) and with full memory limit(
   512M).
 * Now I can see a lot of this errors:
 * PHP Fatal error: Out of memory (allocated 501219328) (tried to allocate 32768
   bytes) in /autoinstalator/wordpress8/wp-content/plugins/easy-wp-smtp/vendor/woocommerce/
   action-scheduler/classes/abstracts/ActionScheduler_Lock.php on line 1
   (with different
   paths)
 * I’ve checked backup file by Traktor tool – it is fine.
 * Is it possible to disable all plugins in the backup and restore without any plugins
   at all?

 * Plugins and themes are activated *after* the database has been restored. Most
   likely, all your data has already been transferred. Try to enable WP_DEBUG and
   see what errors you get.
    Out of memory -> increase memory_limit to 1G
