Creating Session

Hi,
So i am currently having a weird issue which i cannot fix where i will create my session and it will create perfectly fine when i have steam closed when creating the session in the stand alone game instance, however when i try to create the session when i have steam open using the stand alone game instance i encounter an issue. The session creates however it instantly reverts back to the beginning of the game which in my case is the main screen of the menu. When i go to then create the session again it then fails to create and i’m unsure of what may be causing this problem and i’m curious to know whether anyone may know the solution to fixing it.
Thanks .
