Decals in UE 5.8 on Mac

Summary

I’ve downloaded a number of decals directly from Quixel Megascans and they all have the same problem: when I place them, they show as grey planes. I’ve tried troubleshooting this for hours and cannot find a solution.

I am using UE 5.8 on an M5 MacBook Pro. This is not an issue I am experiencing in 5.6.1 using the exact same assets. Any help would be greatly appreciated.

(and yes, material domain is set to deferred decal)
