Steam Overlay not showing up but Steam Client shows game as running (Linux)

I’m trying to setup Steam for my Game following the [Online Subsystem Steam Interface in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community](Online Subsystem Steam) Docs.

After following all the steps and trying to launch the game in Standalone or a build version, I can see in the Client that i’m playing Spacewar (480) like i set in the “steam_appid.txt” but the Steam overlay won’t open.

I’m a bit clueless what could be the error here and hope maybe you have some ideas.

Hello,

Same here. And no error in log. The exact same code works displaying the Steam Overlay on a Windows computer/build (with Proton).
Did you figure out a solution ?
