Steps to Reproduce
- Open UEFN project “Omnia_the_Broken_Kingdoms”
- Click “Lancer la session” (Launch Session) to start a play test
- Local validation runs and fails with a content-service error
- Error references module ID e53eb8de-4067-1c4f-b791-349f288795b2, which does not exist anywhere in the local project files, plugins list, or the 47 referenced Fab assets
Expected Result
The project should validate successfully and allow launching a play session, as it did before this issue started occurring.
Observed Result
Validation fails every time with:
ErrorCode=errors.com.epicgames.content-service.module_not_found
Path: /api/content/v4/module/e53eb8de-4067-1c4f-b791-349f288795b2/version/1/staged-files/public/api.json
Already tried without success: clearing/rebuilding local sync cache, verifying Fortnite game files via Epic Games Launcher, toggling Scene Graph experimental feature, restarting UEFN multiple times. Epic Games player support confirmed they don’t handle UEFN issues and redirected me to this forum.
