Auto removal of physical objects?

In my game there are physical 10 objects and a camera that follows one of them.There is no code in the game that deletes anything. All objects are created at the beginning of the game. In my code there is nothing other than creating objects and moving the camera.
The problem is that my game constantly crashes in 1-5 minutes on Android. But on web, there is no such problem.
I tried to debug the game through Android studio, and every time an error in different places of physics, for example, a broken pointer to a fixture or body.

Is it possible that the engine removes nodes that are not in the camera?
Any guesses?

Thanks for any help
