UEFN Running, But Editor Does Not Open

General Issues and Bug Reporting

Summary

When I attempt to launch UEFN, the loading splash screen appears, but when loading completes, the editor does not open and cannot be accessed. Epic launcher states that UEFN and Fortnite are already running until a “Fortnite” background process is terminated in Task Manager.

Currently using a Windows 11 laptop; may be something on the OS or hardware end, but UEFN did not have any problems on this laptop before (last time was about 2 weeks ago)

Specs:
Windows 11 Home v.10.0.22631 build 22631, x64
Intel i7-14650HX, 220 Mhz 16-core
NVIDIA GeForce RTX4060 Laptop
32GB RAM

Attempted the following:
-Restart computer; no change
-Validate files; no change
-Reinstall; no change
-Open UEFN .exe from install location, including as administrator; no change
-Find and resume URC in resource monitor; URC is not suspended, not running when UEFN is not running

Update: The most recent UEFN update now yields a crash report, citing a GPU crash dump. However, this error seems to be happening for most other users.

Update: Case closed. I found that my laptop was defaulting to less-capable, integrated graphics, rather than the 4060. I’m not sure if this was causing the issue before the update, however.

Mentioned just earlier, but I was able to find a fix. Turns out it was a GPU issue. So if you’re still having trouble, check to make sure your drivers are updated, that your GPU is up to task, and that your system is using the GPU you need.
