My Unreal progam keep crashing??

While working in landscape mode. I’d be sculpting and adding tiles and then Unreal Engine 5.1 automatically crashes suddenly and a message appears saying, “GPU Crashed or D3D Device Removed.” I look it over with a friend of mine and he thinks my OMEN LAPTOP that I’m running Unreal on needs more RAM. Any ideas on how I can install more RAM into my OMEN Laptop? Any advice would be greatly appreciate; because the Unreal tech Support center is down :frowning:
