Do you know exactly your videocard model ?
So I did a little digging because its not clear on the system hardware. It's an AMD Radeon 780M GPU which is part of the AMD Ryzen Z1 Extreme processor. So, it's an integrated GPU, if that helps.
Well, you need at least +6 VRAM dedicated GPU to launch games with high-end visuals on Unreal 5,
You need DX12 discrete GPU: 6 GB VRAM minimum (NVIDIA GTX 1660 Super / RTX 2060 / AMD RX 5600 XT / RX 6600). Better 8 GB (RTX 3060 / RX 6700).4Gb VRAM GPUs may run or not, it's more risky.
