Hi everyone,
We have encountered an issue with opencast-13.2.0 where some events can´t be deleted in the admin-UI.
In the UI i can see that after i ran the delete-workflow theres still an publication on engage.
When i click to watch the video on the engage-player (paella) the video can´t be loaded.
Furthermore the event still holds two attachments: security-policy-episode & security-policy-series.
If i re-run the delete-workflow i can see the following in the logs:
```
2024-04-09T12:32:36,708 | WARN | (RetractionListener:63) - The retract workflow "Delete" (id: 589147, created by: <user>, media package c127ccd2-be77-415b-8f6a-577d43f89956) has some non-retracted publications, refusing to orphan them.
```
This only happens with some events/videos. To me it looks like the two attachements are not deleted properly and cause this event to be stuck in the admin-ui.
Seems to be kinda the same issue like:

Thanks in advance for your help!
Best regards
