Unreal Editor for Fortnite

What Type of Bug are you experiencing?

Stability

Summary

Sometimes UEFN just freezes when i push some changes or load a map and change the focus to another window with alt + tab. Then i have to kill the UEFN task (which is called “Fortnite”, like the game) and the “urc” task (i guess that’s something related to the Unreal Revision Control?). When i restart UEFN afterwards without closing Fortnite, Fortnite often crashes with an EAC Violation message. Not sure if i run risk getting banned for launching UEFN (it definitely is triggered by launching UEFN and nothing else).

Steps to Reproduce

See Summary.

Expected Result

UEFN should just start without Fortnite EAC triggering any violation errors.

Observed Result

EAC violation, Fortnite crashes

Platform(s)

Windows 11
