In a dynamic slice, the canvas script does not fully work

I am trying to make a shot a sphere with a dynamic slice. A script with an impulse is installed on the sphere and the impulse is working, the sphere is flying. but after creating a dynamic slice in and placing it in a spawner object, the script stops working and the sphere simply creates and crashes because it is a RigidBody PhysX. Why does the script stop working? Is this a bug? I watched a lesson with a tank and I repeated the same thing. But it never worked. The sphere falls simply, although if you do not put it in a dynamic slice, everything works
but then I can’t shoot many times. I would like to use a spawner
Help!
