Unable to launch UEFN if Fortnite is running (and vice versea)

Unreal Editor for Fortnite

What Type of Bug are you experiencing?

Other

Summary

My workflow for the last several months has been to launch Fortnite and then launch UEFN (both for Epic games launcher). Then inside UEFN I had my “Launch Session” properties set to “Connect to Platform”. However, starting today once you launch either UEFN or Fortnite, the Epic games launcher considering them both to be running and prevents the other from starting (worst case is you have Fortnite running and then you cannot run UEFN at all).

Steps to Reproduce

Launch Fortnite via the Epic Games Launcher
Attempt to launch UEFN

Expected Result

I should be able to launch UEFN if Fortnite is running, and vice versa.

Observed Result

Both UEFN and Fortnite switch to “Running” in launcher
UEFN however is not running/accessible
Attempting to start UEFN from the Library doesn’t work
Attempting to start UEFN from the right click menu on the task bar widget results in a silent failure/ignored action

Platform(s)

Windows PC

Does anyone have any workarounds to this issue?

also running into this issue! Very annoying if you’re working on an experience and want to help your team test on Fortnite.

The status of this incident has been moved from ‘Awaiting Validation’ to ‘Needs Triage’.

I think I came across a workaround. My issue was that I could not test my UEFN game. I would launch UEFN, and then I would launch Fortnite using the Epic Games Launcher. I can’t launch Fortnite with the launcher or even using the exe located using the file system.

I also tried clicking Launch Session and fortnite wouldn’t run. I even reinstalled the Epic Games Launcher not knowing I had to reinstall all my games, so watch out for that lol.

The way I got it work now is I didn’t realize there was another way to test your UEFN game on another computer. I had the option “Connect to Platform” set before, and I changed it back to “Launch on this PC” as in the image:

Finally Fortnite launches correctly, but I still cannot launch it using the Epic Games Launcher like before. Maybe this is intended behavior now, but I had to click the “Launch on this PC” option and it finally launches and correctly connects.

Maybe I just didn’t understand the proper workflow now, but at least this is working for me now. Hopefully this helps another in a similar situation.

This has always been a thing. UEFN and Fortnite are under the same “internal name” in EGL, so EGL sees them as the same game. I’m pretty sure this is intended behaviour by Epic lmao

It’s also why when one is installing the other shows as installing/updating as well, even if it’s not.

I am still getting exactly same issue. Did anybody got the solution.
