UE5 Memory Usage

Why does memory stack upwards of 20GB when live debugging a blueprint at runtime? This is a basic scene for testing with only 1 single Blueprint open on a second monitor for live debugging and the frame rate comes to a painfully slow crawl. Nothing like this ever happened with UE4, anyone know why?

System specs in the photo, but I am using a Ryzen 7 3700x overclocked to 4500 Mhz, 32 GB RAM, RTX 2070 Super.

Never experienced anything like this in UE4…
