Honestly. WTF is this. I CAN NOT OPEN PROJECTS

@davidpkami , have you tried verifying your files and rebooting? Sorry if that’s a dumb question. I am not seeing anyone else experiencing this at the moment.

If me and my team have the same problem since the last update it’s unbearable ^^

I have verified and completed a full reinstall of Fortnite. I can not work in the editor, it is impossible to make the most simple map right now

Do you have contacts at Epic Games? If this is the case, please notify them as soon as possible so that he can solve the problem because it is not possible to work in these conditions, UEFN has new bugs with each update, every time me and my team have always managed to get around this, but this mouse click bug is unbearable and impossible to work with.

hi All,

UPDATE in post number 21 .

The dev @Fire_Tiger369 has found that stopping Discord from running fixes this problem

:+1: :+1: :+1: :+1:

The latest stable version of Discord for Android is 304.7 (as of November 8, 2025), while the latest version for Windows is 1.0.9214 (as of November 11, 2025).

According to Discord Support, a manual update is needed if your Discord is more than 2 updates behind, as automatic updates do work on more than three updates behind.

My Pc Discord is loaded but not running.

Hopefully, this will be useful to other readers. This addresses the problem with UE 5.7 based on UEFN

  1. My 37.* installation had corrupted, showing up during “Verify” of Fortnite/UEFN.
  2. Uninstalled 37.** 38.**
  3. deleted all the C:\Users\%USERNAME%\AppData\Local\
  4. Installed Fortnite 38.10 UEFN
  5. Tried UEFN stalling whilst editing, so this is not the 38.10 installation
  6. Increase my manual page file space to 96GB (96000) from 64GB. Mine stalling slightly
  7. My recommendation is 128 GB (128000), many use a separate SSD and put a Maximum of 512GB
  8. The garbage collector usage has now slowed in the log file, and the response is quicker

Unreal Engine 5.7 production has launched, and people are reporting this problem and crashes.

Many have fixed the problem by adding a 64GB paging file.

Windows 11 appears to be more susceptible to automatic page file issues, which can be resolved by increasing the paging file size.

The size of the memory hardware determines the size of the pagefile.sys

Everything has to run on SSD, and UEFN PROJECTS MUST NOT RUN ON ONDRIVE.

Use of C:\Users\%USERNAME%\Source\repos\Documents\Fortnite Projects is guaranteed to work by Microsoft, as it’s the same as what Visual Studio 2022 uses.

C:\Users\%USERNAME%\OneDrive\Documents\Fortnite Projects WILL CRASH if the OneDrive network fails, and will cause VSCode/Verse to lose to red underline on errors.

Make sure the Unreal Revision Control is NOT using OneDrive

Windows 11, by default, is OneDrive C:\Users\%USERNAME%\OneDrive\Documents

This test used the UEFN Feature example Alpha Tycoon on 38.10
