I have a game that is built in multiple different Unreal Versions: 4.27, 5.3, 5.4, 5.5, and 5.6. I run each version of the game on an XBox. However, only the Unreal Version 5.6 fails with the XBox error code of: [E\_XBL\_NOT\_INITIALIZED](https://learn.microsoft.com/en-us/gaming/gdk/docs/reference/live/xbl-hresult-error-codes#xsapi), which should mean that [XblInitialize](https://learn.microsoft.com/en-us/gaming/gdk/docs/reference/live/xsapi-c/xbox_live_global_c/functions/xblinitialize) was not called, but it was.

I have reached out to Microsoft/XBox reps and they are reviewing our logs, but they also asked me to reach out to Unreal, to ensure there isn’t something that changed.
