Hey,
I fixed the map’s missing error and defaultengine.ini had these:

[OnlineSubsystem]
DefaultPlatformService=Null
	 
[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480

[OnlineSubsystemNull]
bEnabled=true

and I added

[/Script/OnlineSubsystemUtils.OnlineEngineInterfaceImpl] bUseOnlineServicesV2=false
but still have the same issue.
the logs are attached too.
