New to Unreal, not sure what is slowing down my performance

Hi all: I’m very new to Unreal Engine 5 and I’m trying to figure out exactly what is slowing my game down. I know it has to do with some of my actors, because it gets more laggy the more I spawn. I have pretty good hardware, so I don’t think that is an issue. I tried looking at the insights, but I’m not really sure how to go from there. I’m using the Top Down template. Any help is greatly appreciated!
