Weird Quicklook behaviour

I’m getting strange Quicklook behaviour on 13.6.1 all of a sudden: previews stop working, after a few tries show just the text contents of glyphs files, and then refuse to preview at all. This is spammed in the console:

Sandbox: deny(1) file-read-xattr /Users/path/to/file.glyphs
Sandbox: deny(1) file-read-data /Users/path/to/file.glyphs

Any idea what’s causing it? I reset QL, relaunched Finder, it helps for a moment and then starts again. Updated to 3234, doesn’t seem to make a difference.

There is also stuff like this [ArcadeSummary] Could not find app metadata for: com.GeorgSeifert.Glyphs3 maybe it’s related somehow.

I’m not sure what causes this. Seems like some permission problems? Maybe run Disk Util?
