Deleted objects not shown in WebIF anymore

Hello,
I’m facing a problem with my NC Installation:
When I delete files/folders, they are not shown in the deleted objects anymore.
This behaviour is since i deleted the trashbin using: “occ trashbin:cleanup”.

The cleanup process worked without an error, or so… but since then, nothing is
shown in the deleted objects anymore.
The deleted files are present in the “…/files_trashbin” directory, and with
“occ trashbin:restore” I’m also able to restore files from there.
But the Trashbin in the WebIF isn’t working anymore.
It always just tells me, that there are no deleted files or folders by now.

There are no entries in the log regarding these problem.

[/details]

Nextcloud version (eg, 20.0.5): 27.1.6
Operating system and version (eg, Ubuntu 20.04): Debian 12.4
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.57
PHP version (eg, 7.4): 8.1

Hope anyone can help me with this problem.
Many greetings and thanks for great work on NC
Andi
