Hey everyone,

I know this is a somewhat old topic, but Iā€™m currently facing issues with UEFN and could really use some help.

I downloaded UEFN from the Epic Games Launcher, but when I try to run it, the launcher shows it as ā€œrunning,ā€ yet nothing actually opens. However, if I launch Fortnite separately, I can log in and play without any issues.

Iā€™ve tried every fix I could find onlineā€”verifying files, reinstalling, copying the UEFN files to the Fortnite directory, moving the UEFNWin64.exe to my desktop and launching it, and even running it as an administratorā€”but none of these solutions have worked.

Has anyone experienced this issue recently and found a fix? If you have any suggestions, Iā€™d really appreciate it!

Iā€™m currently trying to run UEFN on an EliteBook 745 G6 with an AMD Ryzen 7 PRO 3700U and Radeon Vega Mobile Gfx (2.30 GHz).

Thanks so much in advance for your help!
