Upgraded from 4.27 to 5.0.3 Compiled Game works, Run Standalone from Engine doesn't

Development Programming & Scripting

Hi,

it took me a while to get it working, but I’ve upgraded our project to unreal 5.
Side info: I recreated all structs from scratch.

I can compile and run the game but can’t run it in engine.
Thanks for help.
