Created attachment 150183 [details] Dolphin thumbnail fail
Can confirm. Probably the file format changed enough for the thumbnailer to start failing.
Still no preview with recent Blender 3.5.1 and latest kio-extras 23.04.
Can confirm
Blender ships its own thumbnailer. This can be fixed by adding this ``` [Thumbnailer Entry] TryExec=blender-thumbnailer Exec=blender-thumbnailer %u %o MimeType=application/x-blender; ``` to ~/.local/share/thumbnailers/blender.thumbnailer
