Unreal is crashing whenever I try to open the project settings. It looks like it has something to do with the IPhonePackager.exe. The file is definitely there.
I’ve tried deleting the contents of Saved/Config, and still get a crash. Samething happens for a clean project as well.
Unreal was compiled with Clang 3.9 in case that helps.
