Can't launch Fortnite separately if UEFN is running since this update

Please select what you are reporting on:

Unreal Editor for Fortnite

What Type of Bug are you experiencing?

Stability

Summary

Our project takes around 40 mins to launch. I don’t want to simply wait that to see something inside Fortnite’s shop or a new gamemode like Reload. However, the exe wont work as it used to, now it tells you to use epic games launcher, which is annoying. The epic games launcher shows fortnite is running, when its not, because it thinks UEFN is also Fortnite. The latter is a bug never fixed and now the whole thing is just inconvenient.

Steps to Reproduce

Open UEFN
Try to launch FN separately (no live edit)

Expected Result

You cant

Observed Result

Exe opens up FN like it used to.
EGL doesn’t show FN as running when its not and you can launch from there too

Platform(s)

pc

I am having the same issue and no resolution and the game will not load, ever.

this will never be fixed, it’s been an issue since UEFN came out and they never say they’re going to fix it.

This bug is starting to make me wanna cry so hard… This is because UEFN is considered a part of Fortnite…


The point is that UEFN and Fortnite are even crashing a lot with latest update (Fortnite crashed like 10 times in 5 hours, with DX12) and everytime Fortnite crashes, I have to restart UEFN too, because Fortnite will only launch with UEFN closed.
Hopefully they make UEFN a standalone program and not an add-on of Fortnite because this bug duplicates, triplicates time spent working…

Yeah its been around 3 updates they did this and its the worst QOL they could have done, as well as preventing the .exe to run directly without Epic Game Launcher. Now its triple the time to do the same thing, and it causes more headaches for no reason.

Have you guys found a workaround for this? I can’t launch Fortnite if UEFN is running and vice versa. Have to restart my computer every time :frowning:

hi @Wertandrew @GraemeBB and All.
You must enable the shortcut in the picture below

It would be best if you did this for UEFN and then Fortnite
All the problems with using DX11 SM5 were solved in

[Solved] How to fix Fatal Errors in UEFN related to Graphic Cards and Shaders and Derived Data problems - General / Issues and Bug Reporting - Epic Developer Community Forums

? This didn’t solve it, I still can’t launch the client while the editor is open also this thread is unrelated afaik to the graphics cards/shaders, its about running fortnite from the binaries folder/because fortnite is seen as running in the EGL when uefn is open

hi @Mineblo ,
On my Windows 11 laptop Opened UEFN from the Shortcut created by EGL.
Typed Windows Key +D to bring back desktop
Open Fortnite 32.11 with the Fortnite shortcut created by EGL

You cannot use
C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping_EAC_EOS.exe

You Cannot directly start Fortnite from The Executable as the Anti Tampering code must be downloaded from AWS servers

you must use for fottnite

com.epicgames.launcher://apps/fn%3A4fe75bbc5a674f4f9b356b5c90567da5%3AFortnite?action=launch&silent=true

for UEFN its simply replace current target by

"C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\UnrealEditorFortnite-Win64-Shipping.exe" -d3d11 -sm5 

They are both running in the background as typing.

This is not a RTX 4090, its q low end HP Laptop therefore

It does not seem to work for me. are you sure you didn’t open fortnite first and then uefn?

Hi

Both ways. Long time ago the was a problem where opening Fortnite could not login in UEFN withoyt running as administrator, bu that was UE5.4

Try adding massive page file. Look in Task Manager and see if you have 16GB free
mines 19.7 of 39GB with both running

UEFN has no issue opening / logging in. Its the only thing here that actually has no problem launching whenever, Its the Fortnite Client itself this post was made about regarding how it’s not possible to launch fortnite while uefn is open
