Build Problem with Entities Preview 23

Yeah, what shall i say.
I don't have any #if Unity_Editor, but whenever i build, i get sth. like this:

Code (CSharp):

1. PlayerConnection initialized from D:/Projects/Starlord-TheCockpit_18.3/build/RenderMeshCockpit_Data (debug = 0)

Currently it's just the model and a hybrid approach with position, rotation and scale

Has to do something with my project setup ! ...
I just took away another project, put everything in it, build it, and go fine.
But this "solution" didn't come into my mind for a quite long time...
