Unreal c++ Co-Op Game SubsystemName Null on Launch

Hi there!

I’m working with Unreal Engine 5.2 but I have a problem connecting to Steam. I’ve got everything set up in my DefaultEngine.ini and Build.csfiles, and the plugin is active, but when I run the game as it said at the end of lecture 3.6 , the Steam subsystem still shows asNULL` .

I’ve checked the following:

  • Steam is running, and I’m logged in.
  • Steam overlay is enabled.
  • The correct Steam App ID is set ( 480 for now).
  • OnlineSubsystemSteam is enabled in the plugins.
  • All necessary modules, like "OnlineSubsystem" and "OnlineSubsystemSteam" , are included in the build file.

Could you help me figure out what’s missing or what I might be doing wrong?

Thanks in advance!



Problem solved with the Batch Script in the next lecture.
