image preview does not open

[shalmaxb]

In a new installation with most recent version, I cannot open the image preview, nor from list view nor from detail view. No log messages.
Where could I search?

Have you tried it in different browsers? What is displayed in the browser console at this time?

It says, that a preloaded font cannot be loaded. I already switched to the default theme (I used another before), cleared all caches, started again. Switched browser. But does not work so far.

Die Ressource unter "https://xxx.de/client/fonts/inter/Inter-Regular.woff2" wurde vorab geladen ("link-preload"), aber nicht innerhalb der ersten Sekunden verwendet. Es wird eine Überprüfung empfohlen, ob alle preload-Attribute korrekt gesetzt sind. 

This is the message, which appears several times.
