Weird Lighting Bug (Mac)

I’m completely new to UE4 and I’ve been trying to mess with the default templates but I keep getting this lighting bug. In this video I just made a new default 3rd person level, changed nothing, and pressed play. I think it might have something to do with my mac because I have the M1 chip and I know that it isn’t the best thing to be running UE4 on.
This bug happens in every 3rd person level I make, and I have a different lighting issue in first person levels. Anyone have an idea on how I could fix this?
