Hey Everyone, I’m having some issues upgrading my C++ project from UE4.18.3 to 4.19.2
I already tried rebuilding the solution and regenerating visual studio files. I also tried all of the steps here to no avail:
This is the error I’m getting when I try to upgrade from the unreal engine launcher:
Project files could not be generated. Log output:
Running G:/Program Files/Epic Games/UE_4.19/Engine/Binaries/DotNET/UnrealBuildTool.exe -projectfiles -project="G:/Documents/PunchBombBackup/2018-04-07/PunchBomb 4.19/PunchBomb.uproject" -game -rocket -progress

While compiling G:\Documents\PunchBombBackup\2018-04-07\PunchBomb 4.19\Intermediate\Build\BuildRules\PunchBombModuleRules.dll:
ERROR: g:\Documents\PunchBombBackup\2018-04-07\PunchBomb 4.19\Source\PunchBomb.Target.cs(8,9) : error CS1729: 'UnrealBuildTool.TargetRules' does not contain a constructor that takes 0 arguments

ERROR: UnrealBuildTool Exception: Unable to compile source files.
And this is the error I’m getting when trying to convert by right clicking the unreal project file:
Running G:/Program Files/Epic Games/UE_4.19/Engine/Binaries/DotNET/UnrealBuildTool.exe -projectfiles -project="G:/Documents/PunchBombBackup/2018-05-03/PunchBomb 4.18/PunchBomb.uproject" -game -rocket -progress

Anyone run into anything similar or have an idea on how to fix it? I need to upgrade to get the project working properly on Windows Mixed Reality (doesn’t play nicely with SteamVR in 4.18.3 apparently)
