AutomationUtils.Automation.dll Locked, Cannot Package

I was able to package my project and now I suddenly cannot. I have tried many variations, reverting, restarting, etc and cannot get my game to package. I have tried other projects and they work. I have also tried restarting my engine.

Any thoughts?

As a workaround I launched the project from the EPIC Launcher and was able to package from there (I also had to turn off my antivirus which I didn’t need to for previous successful builds (Bullguard AV)).

VS2015 (devenv.exe) was holding onto AutomationUtils.Automation.dll and not letting it be used for packaging.
