I’m also having trouble with the many bugs in Unreal Engine. There are still problems that I can’t solve, and the build results are different every time even with the same source code. I used to use Unreal Engine on a Mac, but the package build was strange so I switched to Windows. In my environment, Windows seems to be more stable than Mac. The city sample is a large-scale project, so it must be difficult for the developers. I think Unity is more stable than Unreal Engine. Also, have you tried deleting CitySampleCookedEditor.Target.cs? > [@Targets with a unique build environment cannot be built with an installed engine.](https://forums.unrealengine.com/t/targets-with-a-unique-build-environment-cannot-be-built-with-an-installed-engine/1353217/3): > > In the case of City Sample and UE 5.3.2 that line doesn’t exist in any .Target file and I even tried doing “BuildEnvironment = TargetBuildEnvironment.Shared;” in all .Target files and nothing changed, I still can’t generate the project files. --- _[View the full topic](https://forums.unrealengine.com/t/packaging-failed-sdk-various-issues/2346079)._
