I want to integrate Steamworks in my project (4.15) and have try many methods and times of days here. The online subsystem works perfectly in standalone. But it’s easy to create a package. If I deactivate the online Steam subsystem with plugins, the packaging will work fine again.

I’ve tried that, for example

> **[Online Subsystem Steam](https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Online/Steam/)**
>
> An overview of Online Subsystem Steam, including how to set up your project for distribution on Valve's Steam platform.

and that

Same problem in blank project, but not in a newer version. In 4.18 the substem works fine in a blank project. But my game project is not compatible witz 4.18

After days of trying and failing, it finally works. Unfortunately, I can not say exactly what the problem was. I solved it by verifying the engine in the epic launcher.

For me, this was caused by replacing Steamworks SDK in the Engine/ThirdParty/Steamworks directory. I believe ever since UE 4.7, you don’t have to manually download the Steamworks SDK. Once I verified the engine from the launcher, the old files were restored and I could package without any issues.
