Help with unreal editor 4.18.3

Unreal Engine 4.18.3 is initializing up to 45%. Then it pops away and does not open. I have turned my firewall off.

My Mac specs are:
iMac (retina 5K late 2015)
processor 4 GHz Intel core i7
Memory 32GB 1867 MHz DDR3
Graphics AMD Radeon R9 M395X 4GB

Please give me any suggestions on fixing this issue. It would be a great help.

How and where did you install the 'Epic Games Launcher?

Do you get a error or something?

For now I can give you a few thing that can help.

  1. Run The download as administrator.

  2. Reinstall Epic Games. Download - Unreal Engine Make sure you get the launcher directly from original source.

I hope this will help you.

I got Epic Games Launcher from Unreal Engine herunterladen - Unreal Engine
And no error displayed. Unreal Engine 4 only initialized 45% even with about 12 attempts.
