Game Objects don’t appear on build but they do in the Scene and Game tab

I’ve been looking for a solution to this for a while. I’m making a rhythm game for mobile and the notes that move appear in the Scene and in the game tab, but when I build the notes simply do not appear. I already did everything to try to solve it, I tried to change the camera, the order of the objects, the layers, the code, the Unity settings, make another scene and copy it, but they do not appear. I’ve been looking for a solution for a long time.

In the image on the left, the game is running on unity, the notes appear normally, on the image on the right, the game is running on the cell phone, the notes do not appear.

Please does anyone have a solution, I’ve been trying to find a solution for a long time.
