Level goes dark on creation and load in

As I am quite new to Unreal Engine, the solution to this issue could be super obvious. Anyway, when I load certain levels (or create any new ones) they always go dark in the viewport and when I run it. I’ve done things on a certain level on the laptop it was originally created, but when I run it on my desktop computer it just goes dark. Sometimes, when I created levels on my laptop it also ended being dark.
If needed, here are the specifications of my computer and Unreal engine:

Version 4.27.2 (on both computers)
CPU: I5-13400f
Mobo: Z790
GPU: RTX 4070
RAM: 32GB DDR5
Storage: Samsung 980 Pro 2TB

Any help would be appreciated.
