Focal Point Feature is missing

What can be the reason if the “Focal Point Feature” is missing? I have the exact same installation on two different servers, on one system I can set the focal point, on the other the button is not displayed without any error.
Uploading and image manipulation (cropping) is working on the server. Configuration file looks the same. Data is also the same.

Do both intallations use the same Kirby versions? Which versions?

Both Versions are using Kirby CMS 4.3.0 and PHP >= 8.3.

And focus is not disabled in the file template(s) of the corresponding files?

OK, it seems that time has solved the problem. It works now without us changing anything. You have to believe me :sweat_smile:
Thank you again for your fast support.
