Unreal Editor Crashes randomly

#1

Randomly when I’m using UE 5.1, the editor will crash, not when I’m doing anything specific, just randomly. I have tried searching the problem but I haven’t found any fixes that worked.

I have tried:

  • Editing the tdrdelay registry keys to make them 60
  • Ensuring graphics drivers are up to date
  • Resetting my nvidia control panel settings
  • Updating my bios
  • Updating Windows
  • Obviously restarting my computer
  • Ensuring that the problem wasn’t related to just one project.

The error log goes as shown:

Fatal error: [File:D:\build\++UE5\Sync\Engine\Source\Runtime\RenderCore\Private\RenderingThread.cpp] [Line: 954] 
Rendering thread exception:
Fatal error!

Crash in runnable thread RHIThread

This looks like a driver issue. Make sure you are up to date with your gpu drivers. I see you mentioned this and that you have nvidia which means you’ve tried this. I did see on another thread that setting the project to use dx 11 solved their engine issues. That may be worth a try.

#3

Okay, I just tried that however, I did randomly crash again, this time with no crash log though. Not sure if it was a fluke or not.

EDIT

Can confirm, this is not a fluke, it has happened multiple times now. Still no crash log.

EDIT 2

I got an error this time, it goes as follows:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000144ab0000

Ok. In this instance, it could be an issue with the install.

I assume you are not using a preview release. If so, switch to 5.2 as 5.3 will most likely have issues.

The, try a repair of the install and if that fails, remove the install for the given engineand ensure the folder is empty on your machine for that version before reinstalling. Also perform a minimal install (no extras like android etc) and see if that works.

Just reinstalled the editor and played around with a project for a bit. So far no crashes, I think it worked. Thanks so much for the help.
