Unreal Engine 5.1.1 - Problem with spawning an actor at different packaging config

Hello everyone,

I have a problem with Unreal Engine 5.1.1.
When I travel to my game-level with the development-packaged project, the enemy-characters are spawning, chasing me and everything is fine but when I try to play the game in the shipped-packaged-mode, the enemies are not visible. The weird thing is that I hear them but they aren’t visible.

Anyone else got this problem?
