Problem of no objects in the loading scene

[LIVEOW]

I am a Chinese. I can only use a translator. I'm sorry, reading my article might be a bit difficult for you. I'm extremely sorry. When I'm running the game and loading the scene, only a little bit of items are added to the scene, and it cannot be fully loaded. The scenes I created myself also cannot be used and loaded normally. How to solve this would be very helpful to me. Thank you very much.🤕
