Nativization "cycle node" error

Guys please
when I use Exclusive nativization in 4.19 and package and then stat the game, it crashes and I get this kind of error on multiple classes

Cycle Node
But what does it mean?
When I use Inclusive nativization, it works but it only nativizes Parent classes
child classes of created Parent classes do not get nativized
But when I use exclusive nativization I get these errors even on the classes that get nativized using Inclusive method
