UE4 Launcher stuck on 83%

Hello everyone. Today, when I launched UE4, it did not launch. It got stuck initializing at 83%. Please help!

I have same problem =(

I had a similar issue, but for me, the fix was actually to disable a plugin I have in Visual Studio called “Entrian Auto Attach” - it usually works fine to auto attach to the editor .exe when it launches, but for some reason, it was stopping the engine from fully launching…
