Why did links to bitrix stop opening?

Question

1C-Bitrix

When you click on a component element (be it a catalog or a list of news), the correct link is written to the URL, but the general catalog page opens. At first I thought that the problem was only in the directory. I dug up the CNC, here are the settings:

Component settings:

And then I clicked on other links and realized that other links do not work either. Here is the code from urlwriter:

<?php
$arUrlRewrite=array (
  3 => 
  array (
    'CONDITION' => '#^/catalog/#',
    'RULE' => '',
    'ID' => 'bitrix:catalog',
    'PATH' => '/catalog/index.php',
    'SORT' => 100,
  ),
  0 => 
  array (
    'CONDITION' => '#^/rest/#',
    'RULE' => '',
    'ID' => NULL,
    'PATH' => '/bitrix/services/rest/index.php',
    'SORT' => 100,
  ),
  2 => 
  array (
    'CONDITION' => '#^/news/#',
    'RULE' => '',
    'ID' => 'bitrix:news',
    'PATH' => '/news/index.php',
    'SORT' => 100,
  ),
);

404.php is installed, but if you call test.ru/404.php, the catalog page opens. All character codes are filled.
