UEFN - Not authorized to access Lore repository - Launch Session fails for one project

Summary

UEFN Project-Specific Lore Repository Authorization Failure

I am unable to Launch Session for one specific UEFN project called “Escape_50_Rooms”.

My other UEFN projects launch successfully using the same Epic Games account, so this appears to be specific to the repository associated with this project.

When I attempt to Launch Session, project validation fails. The Output Log shows the following error:

[36d7a948-be9e-4500-bdc3-344de45f7199][Push] failed in 0.45 seconds

[36d7a948-be9e-4500-bdc3-344de45f7199][Push] Not authorized to access repository

at Z:\devel_work\urc\Lore\lore-transport\src\quic\storage_service\client.rs:237:51
at Z:\devel_work\urc\Lore\lore-revision\src\branch\push.rs:400 - opening storage session

Repository/Module ID:
36d7a948-be9e-4500-bdc3-344de45f7199

The project validates its assets until it reaches the repository push, where the push fails because I am “Not authorized to access repository”.

I have confirmed that another UEFN project on the same Epic Games account can successfully Launch Session.

I have also completely closed UEFN, cleared the contents of:

%LOCALAPPDATA%\UnrealEditorFortnite\Intermediate\ValkyrieUploadTemp

I then restarted UEFN, reopened Escape_50_Rooms, compiled Verse, and attempted to Launch Session again. The problem still occurs.

The project itself is important and contains a significant amount of work, so I do not want to recreate or delete the project.

Could you please investigate the server-side Lore repository permissions for this project and repair/regenerate the repository authorization if necessary, while preserving the existing project and its content?

Project Name:
Escape_50_Rooms

Repository/Module ID:
36d7a948-be9e-4500-bdc3-344de45f7199

Expected Result:
The project should validate, upload its source files, and allow Launch Session.

Actual Result:
Project validation fails because the Lore repository push returns “Not authorized to access repository”.

Thank you.
