Unreal Editor 4.21.2 won't launch on Mac

Hi everyone, we recently tried running the project using UE4.21.2 with Xcode (Mac version 10.14.3) but after 100% compilation (no C++ errors except 1 warning), the project won’t display the editor. However, we do see the taskbar and buttons of the project. We were hoping if someone could help us and guide us if the same problem is faced. Thank you.
