I am not able to play the level, game crashes

Development Getting Started & Setup

when i run my level in “standalone agme” mode the game crashes and i get a crash report:
Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 1039] Attempted to create a package named ‘None’

If I try to do this in “Selected Viewport” mode, the message log shows:
Server failed to login. Login(0) failed with EOS result code (EOS_Auth_ExchangeCodeNotFound)

Has anyone encountered anything similar?

It’s a bit hard to tell what is going on immediately with the context provided. Would you mind sharing your entire log so we can get a better look? Also, was this able to open before or is this your first time opening it?
