Here is the error message

The project could not be compiled. Would you like to open it in Xcode?

I’ve tried uninstalling xcode and unreal and reinstalling them but it still doesn’t work

Im hitting this as well. Not a new project, but Just installing VS 2017. Seems to have broken the vs 2015 install.

Just install 2017, and build with 2015, (Which worked before the install), and your projects are broken.

Also the LocalMapLayoutForCapture is a reference being passed to the lambda as a copy. Probably isn’t going to work worth a darn anyway, its a good thing they aren’t actually using it.
