player Controler not found in shipping build

Hi everybody,
I have a working developement build of a car configurator, but when I build a shipping Version the defaul player pawn gets activated and I am stuck in the floor without the right camera. Any Idea where i could look for a solution? Unreal 5.3, Build runs on Windows, Custom controler
Thanks,
C.

You probably haven’t set the game mode for it. Create a game mode, then override the player controller in it with your own custom controller that you want to use. Then open the level, and in the world settings, set the game mode override to the game mode you just configured.

no that is all set in the project settings. I tried it like you said anyway but no change.
