I found the problem. Turns out that the steamworks sdk version was out of date. I would recommend trying to fix that if you have the same issue like me. You can update it to the latest version by going into the epic games launcher, clicking the arrow next to the Unreal Engine version you are using, then select Verify.

Hello there @Overseeing_Industry !

Checking through your log, the main error seems to be in the following line:

UATHelper: Packaging (Windows): Unable to instantiate module ‘Steamworks’: steamworks SDK not found in ThirdParty/Steamworks/Steamv153/sdk

This means your build is looking for “OnlineSubsystemSteam” plugin, which in turn tries to include the Steamworks SDK, but it’s missing from your project.

The solution should be simple, depending if you need Steam functionality or not:

  • If you need Steam, download Steamworks SDK v1.53 from partner.steamgames.com and place it in: YourProject/ThirdParty/Steamworks/Steamv153/sdk
  • If you don’t need Steam, then disable the plugin, via setting “OnlineSubsystemSteam” to False, or uncheck the entire plugin from editor at Edit → Plugins

After these steps, please regenerate your project files, rebuild, and try to package again.

EDIT: I see you found a solution, glad it’s resolved
