This was happening before but I also just bought a eGPU for my mac mojave 10.14.5

Dropped in a Radeon Vega Frontier Edition 16 GB  
Intel UHD Graphics 630 1536 MB

My internal GPU is the Radeon Pro 560X which is a bummer so I figured that was why it wasn’t opening the UE  
but alas it’s still not opening…

Even with my internal graphics card (Radeon Pro 560X) I could open the epic games app and play Boarderlands 3 and Fortnite but never the Unreal Engine. And now even with this card I can’t open it…?
