UEFN stuck at 90% after v41.10 update - “Fetching Creative mode profile” / ValkyrieFortnite

Summary

Hi, I’m having an issue where UEFN gets stuck at 90% during startup after the latest update.

The loading text shows either:

“90% - Fetching Creative mode profile”

UEFN never finishes launching.

I have already tried:

  • Clearing the local AppData cache
  • Deleting/renaming the UnrealEditorFortnite local folder
  • Clearing Epic Games Launcher webcache
  • Verifying both Fortnite and UEFN
  • Logging out and back into Epic Games Launcher
  • Restarting the PC
  • Uninstalling and reinstalling UEFN

Fortnite itself launches normally.

I also checked the log. From what I can see, ValkyrieFetchCreativeProfile appears to succeed:

ValkyrieFetchCreativeProfile … step_succeeded
OnlineAccount.Login … operation_succeeded
ValkyrieOnlineAccount … set_account_status Old:[NotLoggedIn] New:[LoggedIn]
Lore login succeeded

However, the editor still remains stuck at 90% and never opens.

This started after the latest update, so I’m wondering if anyone else is experiencing the same issue, or if there is a known workaround.

Please let me know if there are specific logs I should provide.

Steps to Reproduce

  1. Update Fortnite / UEFN to v41.10.
  2. Launch UEFN from the Epic Games Launcher.
  3. Wait for the startup loading screen.
  4. UEFN reaches 90%.
  5. The loading text shows either “Fetching Creative mode profile” or “Loading PostEngineInit modules for plugin: ValkyrieFortnite”.
  6. UEFN stays stuck there and never finishes launching.

I have already tried clearing the local AppData cache, renaming/deleting the UnrealEditorFortnite local folder, clearing the Epic Games Launcher webcache, verifying both Fortnite and UEFN, logging out and back into Epic Games Launcher, restarting the PC, and uninstalling/reinstalling UEFN.

Expected Result

UEFN should finish loading after reaching 90% and open the editor normally.

Observed Result

UEFN gets stuck at 90% and never launches.

The loading screen shows “Fetching Creative mode profile” or “Loading PostEngineInit modules for plugin: ValkyrieFortnite”.

Fortnite itself launches normally. In the UEFN log, ValkyrieFetchCreativeProfile appears to succeed, and the account login also appears to succeed, but the editor still remains stuck at 90%.

Relevant log lines:

[OnlineAccount.Login.ValkyrieFetchCreativeProfile][step_succeeded]
[OnlineAccount.Login][operation_succeeded]
[ValkyrieOnlineAccount][set_account_status] Old:[NotLoggedIn] New:[LoggedIn]
[LogVkScratchRepository] [Auth] Lore login succeeded
[LogSolaris] Cannot process deferred plugins yet, since the Asset Registry is still in the middle of gathering operations/not all modules have finished their loading phases.

hi can you try opening UEFN as Windows 11 “Run as Adminstrator”

like in my post

UEFN will not install correctly from Launcher on any Windows 11 (eleven) version needs to run Elevated "Run As Administrator - General / Issues and Bug Reporting - Epic Developer Community Forums

You may need to login with a shorter username/password

Hi, I’ve been working on Windows 11 and I came to some place else so I was trying to use UEFN on windows 10 computer. Maybe that was causing the problem?

But weirdly it just fixed itself. Like no reason at all. I’m confused. But if this ever happens again I’ll follow your link and instruction to fix the issue. Thank you so much for checking in!
