Epic Broke Unreal Engine 4 - Failed To Launch Editor On Nearly All UE4 Projects

[Alex_Green]

@DacTan88, see this (Config\***Engine.ini):

Missing UnrealBuildTool.exe after build

The problem is in new UnrealVersionSelector in EGS Laucher: Epic Games\Launcher\Engine\Binaries\Win64\UnrealVersionSelector.exe I replaced it (temporary) by another one (from UE 4.27, old sources build) and it’s works now! They updated Launcher and this breaks work with UE4 projects… I need more time to investigate what exactly changed, but I try to do same thing in VM and have same results: UE4 uprojects can’t generate *.sln. P.S. Problem in code (last string): FString FDesktopPlatformBase…
