Files are no longer deleted:Datein werden nicht mehr gelöscht

Error while running background job OCA\Files_Retention\BackgroundJob\RetentionJob (id: 52815816889999361, arguments: {tag:20})
TypeError OC\Files\View::getOwner(): Argument nextcloud/files_retention#1 ($path) must be of type string, null given, called in /var/www/nextcloud/lib/private/Files/Filesystem.php on line 690

Files are no longer being deleted according to the rules. Deleting and recreating the rules did not help. Deleting the Retention app and then reinstalling it also did not change anything.

Expected behaviour

That the files are deleted again in accordance with the rules.

Actual behaviour

Files are not deleted and only the above error message is generated.

Start with OCA\Files_Retention\BackgroundJob\RetentionJob and trace the reported failure through lib/private/Files/Filesystem.php at line 690, then apps/files_versions/lib/Storage.php and FileEventsListener.php. Reproduce the background-job deletion failure and identify why getOwner receives a null path; done means retention deletions complete without this TypeError.
