Line Art doesn't render

LineArtTest.zip (5.0 MB)
Hi guys,
I have used the Line Art Modifier for Grease Pencil for quite a while. But in Blender 3.0 the LineArt kind of doesn’t render anymore. You can see the Line Art in the Viewport and even briefly during rendering. But when the render is finished you can neither see it in the composite nor on the acutal Line Render Layer. Just open the attached blend file and hit F12 to see that the lines are not there after rendering.
Thanks a lot for tips and help.
Cheers
