UE4.22 Won't Launch OSX 10.13

Hi Everyone,

I just installed the Epic Games Launcher and installed Unreal Engine 4.22
However, when I press the ‘Launch 4.22’ Button, the screen disappears and nothing happens.
When I press the Launcher again it shows ‘‘running’’ for a second and then just promptly changes back to launch.

I tried repairing a couple of times and even installing 4.21 / 4.23 but I’m getting the same results.

I work on a Macbook Pro 2015 , High Sierra 10.13.
8GB RAM / 2,7 GH / I5 Core
