@indevd which versions of Nextcloud itself, Tables, and the other apps do you run?

[indevd]

@blizzz Here's the list:

[Nextcloud Hub 25 Autumn] 32.0.5

[blizzz]

Cannot reproduce it on dev branches.

@indevd Do you see anything in the nextcloud.log? Or more likely, any JS errors or warnings in the browser console?

[indevd]

Browser console errors:

and Javascript Warning:

images.js:55 [WARN] viewer: Some mimes were ignored because they are not enabled in the server previews config 
{app: 'viewer', uid: 'admin', level: 2, ignoredMimes: Array(3)}
app : "viewer"
ignoredMimes : Array(3)
  0 : "image/heic"
  1 : "image/heif"
  2 : "image/tiff"
      length : 3
[[Prototype]] : Array(0)
level : 2
uid : "admin"
[[Prototype]] : Object 

No error in the Nextcloud log...

The warning is unrelated, just image formats for which no preview is generated by default. The browser console error do not look like much either. Hm. @enjeck or @silverkszlo do you have an idea?
