Hi everyone,
We are a small game developer studio that is currently working on our first project, and we have encountered a serious problem with the latest version of Unreal Engine.
Our project was originally made in version 4.19, where the game worked perfectly both by running it with the editor and when packaging it into an exe. However, we are now forced to use the latest version 4.21.2 to create a build that works for PS4.
We have migrated the project to the new version, and inside Unreal everything works correctly except for a few errors found in tools that have been updated since 4.19, problems that we managed to solve without further issues.
However, when trying to create a package from the 4.21 version the following error occurs over and over:
UATHelper: Packaging (Windows (64 bit)): LogWindows: Error [Callstack]: 0x0007ffde5e9382b UE4Editor - UWG.d11 !Unkown Function[]
We have tried endless solutions and have looked for info everywhere, but we have been stuck with this problem for 2 weeks.
We have cleaned the project by removing unnecessary files and have tried to make partial builds with only a few elements, but whenever there are blueprints involved the error strikes again.
Thanks in advance
