Composer Loading Screen/images

Hi, i have search in the web but havent found any clue yet.

My scene is loading multiple asset including spine library in the create scene (composer). But the result, it will show black screen for awhile. i have try to put 1 images in the create scene and remove it in the show scene (composer) but it seems doesnt work.

anyone have idea how to resolve this problem?

thanks in advance.
