Unreal Engine 4.17 Released!

I’m getting something similar with my project where UnrealBuildTool fails (with an ArgumentNullException in my case). Not sure if they’re related since I’m able to compile if I do a rebuild but here’s my AnswerHub post anyway in case you want to monitor that as well: UnrealBuildTool fails with null argument - Programming & Scripting - Epic Developer Community Forums

I’ve managed to resolve my issue after stepping through UBT. It looks like changes to Plugin dependencies in 4.17 means lot’s of changes to UBT, and in this case UBT doesn’t handle the exception:

[Resolved] Can't Compile in 4.17
