permanent disappearance and appearance of the object

Hello everyone, I’m making an endless runner on android, there was such a problem: when I start the game on the phone, objects further than a certain distance begin to lag (disappear and appear in a split second). On the first screen, the scenery is visible, to the right of it is an empty space, there should be the same scenery to the edge of the screen. On the second screen, everything is the same, but I caught the moment when the scenery from the first screen disappeared. In the editor, everything works perfectly, I put the project together on a PC - everything also works as it should. P.S. the same situation started happening with the last project when switching from 4.23 to 4.25, but rolling back the engine version is not an option at all)
