I get this error while building uwp project in vs 2017 , unity 2017.1.0f3

Severity Code Description Project File Line Suppression State
Error The command ""T:\Users\ward\Documents\Super Space Serpent SE

Unity\builds\Unity\Tools\AssemblyConverter.exe" -platform=uap -lock=“T:\Users\ward\Documents\Super Space Serpent SE Unity\builds\Super Space Serpent SE Unity\project.lock.json” -bits=64 -removeDebuggableAttribute=False -path=“.” -path=“…\Players\UAP\x64\Debug” “T:\Users\ward\Documents\Super Space Serpent SE Unity\builds\Super Space Serpent SE Unity\Assembly-CSharp.dll” “T:\Users\ward\Documents\Super Space Serpent SE Unity\builds\Super Space Serpent SE Unity\UnityEngine.dll” “T:\Users\ward\Documents\Super Space Serpent SE Unity\builds\Super Space Serpent SE Unity\UnityEngine.UI.dll” “T:\Users\ward\Documents\Super Space Serpent SE Unity\builds\Super Space Serpent SE Unity\UnityEngine.Networking.dll”" exited with code 1.

This project is updated from unity 5.2.4 to unity 2017.1.0f3. I don’t have this issue on a new projects . So i believe it has something to do with the update. All help in understanding why this happens would be appreciated.

After the update to 2017.1.0p4 the error was gone .

I’m having the same problem compiling a UWP Project in Visual Studio.
Anyone have any idea how to solve this?
