Hi @ilozen
To resolve the Epic Games login page issue in your own project in Unreal Engine, try the following:
Look for Project Settings: Look for any project settings related to Epic Online Services or authentication under Edit > Project Settings.
Check Plugins: Deselect any plugins related to Epic services (e.g., Epic Online Services, multiplayer) under Edit > Plugins.
Epic Games Launcher Settings: Ensure there are no settings forcing login on launch in the Epic Games Launcher.
Clear Saved Files: Delete the Saved, Intermediate, and Config directories from your project directory to remove cached settings.
Third-Party Integrations: Check for any third-party services (cloud storage, analytics) which will require authentication.
Version Check: Ensure the project is not problematic because of an upgrade between engine versions.
Editor Preferences: Look for auto-login preferences in the Startup section of Editor Preferences.
Migrate to a New Project: If the issue persists, create a new project and migrate your assets to see if that solves the issue.
This should resolve and isolate the issue.
