BUG: Error by trying to delete assets which are still in use in the media browser

[GuangHa]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When you try to delete an asset which is still in use, you will get an internal error (500).

Expected Behavior

Another message, saying the asset is still in use and therefore unable to delete or maybe disable the delete function.

Steps To Reproduce

1. Open media browser via Property-Editor
2. Try to delete an asset in use
3. Get Error

Environment

- Flow: 8.3.9
- Neos: 8.3.15
- PHP: 8.1.2

Anything else?

It is now fixed in the Neos internal library, but occurs in the media ui package.
See neos/neos-development-collection#5085
