To many Child Actors causing crash?

Hi there,

My project is crashing when I’m opening any level or blueprint.
This is the message I’m getting: Unhandled Exception: EXCEPTION_STACK_OVERFLOW

I tried to track what causes this problem and it looks like it is because I have too many child actors or there is some blueprint that is causing trouble.

My question is, could too many child actors in different blueprints cause this crash?
My computer GPU and CPU is not overrunning when I’m loading a script or starting a level and the game was running all smoothly.

My other question would be how to rebuild my game. Currently, I have different actors that can be placed in the game with all the different child actors attached to them. These actors contain scripts to save variables and also to attach cables to them. I don’t think this will be possible by using actor components or am I wrong with that?
