@sk_10

The #4 is working for Admin Toolbar 3.5.1 and Drupal 10.4.0. #6 is not working. When navigating to `/admin/structure/menu/manage/admin the same error was coming. I followed these steps:

1. Disabled the deprecated Admin Toolbar Links Access Filter and Admin Toolbar Extra Tools
2. I upgraded the admin toolbar from 3.4.0 to 3.5.1
3. Applied #4 admin_toolbar_3493798_4.patch
4. Reenabled the Admin Toolbar Extra Tools module, this worked!

Post drupal core update 10.4.0, few of the admin navigation menus were missing, these were migrated ones might be due to that, readding them fixed it.

The issue still exists in latest 9.5.3 Drupal version https://www.drupal.org/project/drupal/releases/9.5.3 → as well. I have written a custom code on cron run to clear all the orphan files. Its working as expected.

	// Fetch all the orphan files
	$database = \Drupal::database();
	$query = $database->query("SELECT fid FROM {file_usage} WHERE fid IN (SELECT fid FROM (SELECT fu.fid  as fid FROM {file_usage} fu LEFT JOIN {node} n ON n.nid = fu.id WHERE n.nid IS NULL and fu.type =:ids_1 AND fu.count <>:ids_2) as tt)",[":ids_1" => 'node', ":ids_2" => 0]); 
	$resultfids = $query->fetchCol();
	$file_usage = Drupal::service('file.usage');
	  foreach ($resultfids as $fid) {
		$file = Drupal\file\Entity\File::load($fid);
		if($file){
		$usage = $file_usage->listUsage($file);
			if (count($usage) <> 0){
				//Delete Orphan files
				$filename = $file->getFilename();
				$url = $file->getFileUri();
				$file->delete();
				 \Drupal::messenger()->addMessage('Orphan files deleted successfully');
				}else{
		\Drupal::messenger()->addMessage('No Orphan files');
					}
			}	   
		}

I have tested and applied the patch for Drupal 10 setup. This #11 patch works on Drupal 10. Thank you.
