Problem/Motivation

After upgrading the code from Drupal 10.4 to 11.1, trying to run database updates with Drush or at update.php results in this error:

Error: Call to a member function insert() on null in Drupal\Core\Lock\DatabaseLockBackend->acquire() (line 71 of /var/www/html/web/core/lib/Drupal/Core/Lock/DatabaseLockBackend.php)

Presumably other people are not running into this or it would have been reported already, but all the updates are for Drupal core:

It is quite bizarre because the errors are for not finding the database connection, but elsewhere in Drupal, outside the DatabaseLockBackend, it certainly has no trouble accessing the database. I can even get it to run the updates simply by putting an if ($this->database) { check in there; the pre-existing code to go back for another try works fine it seems, but the exception i am getting is not one that was expected.

The same sort of error (query on NULL database) happens in this block, but running the database updates a second time works; clearly it is able to get the database sometimes. [EDIT: Or not so clearly, i think the error still happened after successfully running database updates.]

    try {
      $lock = $this->database->query('SELECT [expire], [value] FROM {semaphore} WHERE [name] = :name', [':name' => $name])->fetchAssoc();
    }
    catch (\Exception $e) {
      $this->catchException($e);
      // If the table does not exist yet then the lock may be available.
      $lock = FALSE;
    }

Let's assume it's a bug for now.

Are you able to create a clean install of Drupal 10.4 and update to Drupal 11 on otherwise the same environment?

So it is not a Drupal Core issue (as i guess i should have expected)— it occurs due to the Drupal 11.1-compatible issue fork of Field Encrypt, specifically the src/FieldEncryptServiceProvider.php file, which is… not mentioned in the field_encrypt.services.yml Huh, did not realize there would be anywhere Drupal automatically interprets something not in Plugins or something like that. Anyhow if there is anything that jumps out to core maintainers for Field Encrypt to fix… #3486465: Make Field Encrypt compatible with Drupal 11.1 by removing eval() and adding a ServiceProvider, use OOP hooks
