UE 4.8.2 crashing when launching editor

I am currently unable to launch 4.8 editor, even to create a new project. It gets to ~34% and then uses 24-28% of my CPU (2-core plus hyperthreading) and quickly consumes up to almost 8GB of RAM. Sometimes it then generates an error report (shared below) and sometimes it continues to run apparently indefinitely, reducing its memory consumption to ~1.3GB. I have submitted the crash report.

I AM able to load 4.7 and 4.7 projects. I AM able to load ARK modding editor.

This seems to have started after:

  1. Install VS 2013 Community Edition
  2. Attempt to install Cubiquity Plugin to new project
  3. Install Epic plugin to Visual Studio
  4. Bluescreen at some point, don’t recall exactly when

Measures I have taken:

  • Uninstall 4.8. Delete 4.8 folder.
  • Remove all 4.8 projects.
  • Scandisk to fix disk errors.
  • Update nVidia graphics drivers with clean install.
  • Remove Visual Studio.
  • Reinstall Visual Studio.
  • Windows System File Checker (“sfc /scannow”)
  • Update from 4.8.1 to 4.8.2.
  • Uninstall Epic Unreal Engine entirely, delete folder, reinstall 4.8.2.
  • Disable antivirus.

System / Environment:
Windows 8.1
Intel Haswell i5 CPU
16GB RAM
nVidia GeForce 970, driver v. 350.12 (tried most recent)
Oculus Rift DK2 with runtime 6.0.1 (tried 5.0.1 and disabled)

Report end!

And of course I finally find the solution!

It was to delete the folder:
\Users\AppData\Local\UnrealEngine

"…delete the folder: \Users\AppData\Local\UnrealEngine "

THANK YOU!!! :slight_smile:

Even before I agreed to let the Launcher update from UE 4.8.1 to 4.8.2,
the Editor had started to Crash (on anything that re-sized the 3D Viewport)
with a misleading Crash Error Dialog about “making sure my Graphics Driver
was up-to-date”!

After deleting that folder, UE4.8.2 had to re-compile all shaders in my project, but now it works!

funny, but I even had recent experience at a studio with its own proprietary game engine,
where senior programmers would e-mail out similar solutions every few months
(dunno why your solution did not occur to me because of that experience, but thanks!)
