Advanced Steam Sessions not working

[GlenZPS]

I am using UE5.3.2, I can’t seem to get Advanced Steam Sessions to work properly, when I start in standalone mode, steam overlay doesn’t pop up.
I have installed both plugins Advanced Sessions and Advances Steam Sessions and they are enabled, I’ve added lines in the DefaultEngine.ini file as well and it is a C++ project, I don’t know what I have been missing.
I noticed that if I have online subsystem plugin enabled, I can create sessions, but if I turn that off, I get an error in the console “uninitialized OnlineSubsystem”.

Hello GlenZPS,

I’m facing the same issue with UE5.3.2, I did the same workflow as you, and Steam overlay does show with Standalone launch in the editor.
And when I package my game I get a Fatal Error when I want to launch it., Did you find a way to fix this issue?

I have exactly the same problem and I don’t know how to fix it.

Add these values to your DefaultEngine.ini

[ConsoleVariables]
net.CurrentHandshakeVersion=2
net.MinHandshakeVersion=2

remove the

; If using Sessions
; bInitServerOnClient=true
from the engine.ini file and it should work

It didn’t work.

I found removing all the indents in the Default engine file fixed my issues.

Go through and backspace a couple of times on all the stuff you had to copy past into the file.

hope this helps
