Graphics not rendered after build

When I build and start, I see that some graphics are not rendered. The build itself works when I just play.
There are no errors and I have a graphic render attached of course.
The only error I got is something about .cfg could not be loaded. I don't know if that effects graphics.

 

I get these two errors idk why. I tried to fix the error myself by creating an cfg but the error didn't disappeared.
