Drupal\Component\Plugin\Exception\PluginNotFoundException: The "tag" plugin does not exist.

Similar for me, after a server upgrade the core/modules/views/src/Plugin/views/cache was missing, so I just rebuilt core

Hi,
trying to get an old website up to speed that is still drupal 9 and I wanted to first update to the latest 9.x release (9.5.11).

However I get the tag-plugin-not-found error:

Uncaught PHP Exception Drupal\Component\Plugin\Exception\PluginNotFoundException: "The "tag" plugin does not exist. Valid plugin IDs for Drupal\views\Plugin\ViewsPluginManager are: " at /var/www/virtual/viesca/test.viesca.de/core/lib/Drupal/Component/Plugin/Discovery/DiscoveryTrait.php line 53"

I already checked the Plugins/views/cache folder which seems to be fine:

$ ls -la core/modules/views/src/Plugin/views/cache/
total 32
drwxrwxr-x.  2 viesca viesca    80 Sep 19  2023 .
drwxrwxr-x. 21 viesca viesca  4096 Sep 19  2023 ..
-rw-rw-r--.  1 viesca viesca 11090 Jul 17 03:00 CachePluginBase.php
-rw-rw-r--.  1 viesca viesca   764 Jul 17 03:00 None.php
-rw-rw-r--.  1 viesca viesca   765 Jul 17 03:00 Tag.php
-rw-rw-r--.  1 viesca viesca  6461 Jul 17 03:00 Time.php

Any other thing i could check?

Ok i got the website running again by running

composer require drush/drush:11.6.0 (other versions seemed to be broken)
drush eval "\$module_data = \Drupal::config('core.extension')->get('module'); unset(\$module_data['views']); \Drupal::configFactory()->getEditable('core.extension')->set('module', \$module_data)->save();" got it from here: https://www.drupal.org/node/157632 → manual module disable using drush
drush pm:install views (reinizializing views)

I hope nothing got lost, but want to rebuild the website from scratch anyway, this was just to extract some information without having the hassle to parse the database directly.
