Hello,

I’m trying to package my project, but it fails each time.

Visual Studio is updated with all plugins.

Tried to find a solution online, but none of them is working.

Here is the log report:

UBA-AssemblyLine-Win64-Development.txt (10.4 KB)

My guess will be on:

UATHelper: Packaging (Windows): J:\UNREAL ENGINE\UE_5.6\Engine\Source\Runtime\Core\Public\HAL\Platform.h(7,1): fatal error C1083: Cannot open include file: ‘type_traits’: No such file or directory
UATHelper: Packaging (Windows): include <type_traits>

But no idea how to get type_traits file
