Unreal Engine Editor 5.3: 'UV Editor' crashing entire engine

General Issues and Bug Reporting

Hello everyone,

This is my first post, sorry for any eventual mistake!
I have been using Unreal Engine for a little while, and last week i started having issues with the ‘UV Editor’; it always crashes the entire editor as soon as i press the uv editor button.
The above happens with any scene, even a blank scene with only a cube in it; the funny thing is that this behaviour started all of a sudden when i was working on a project. * tried to install Unreal 5.3 on my laptop, and despite the laptop being old and not meeting the minimum requirements, when i try to open the UV Editor everything opens fine with no crashes.
My pc has got Windows 10, all updates and updated NVidia g.driver; i also tried to reinstall the entire Uhnreal from scratch (after having uninstalled and deleted every trace of the previous install) but this error keeps happening.
Something seems to have happened last week, perhaps a Windows update messed Unreal 5.3.2 up?
I get the following error, with request to send to Epic "An Unreal process has crashed: UE Tryout’, with the following report:

The crash happens with either directx11 or 12.
I have a file generated by the crash, but i seem unable to attach it here.

Does anyone have any idea of what could be causing it? My guess is some sort of update got in the way, but the laptop i have tried it on has got the same updates, just different hardware.

Thank you very much (and sorry if i have broken any forum rules!).

Hello, this looks like a source file issue:

  1. I would reinstall/verify Unreal Engine as the first step.

  2. If this doesn’t work, you can try updating your GPU Driver (I doubt this would work, because the error does not indicate, to me, a video driver issue… HOWEVER, that could be because this error/crash prevents communication with the GPU, in which case, you could get ANOTHER crash error after reinstall/verifying.)

  3. Someone mentioned disabling RAYTRACING. (Can anyone help me with this error? 1074 assertion failed, shared pointer.. - #7 by pgaleone)

Odd, but I’d try these in this order.

Hello,

Thank you for your suggestion!
After having reinstalled everything and updated drivers etc, it was still crashing; somehow it seems that it was grabbing some sort of config file from the previous installation.
Despite me having carefully deleted everything from the registry and on the hard drive, i said myself ‘well, lets do that again!’, and this time after having deleted the old files from the '/user/ directory, it fixed itself.
My guess is that i must have done something with the actual UVEditor window (positioning or similar) that have cause this behaviour. :thinking:

There’s a million reasons why any one thing can go wrong. I damnnear have a panic attack anytime I come across an error.

I’m genuinely glad you figured this one out.

I have the same symptoms as you, where exactly should I erase it?

Hello,

Sorry for this late reply! I didn’t get any notifications…
What I did was to uninstall Unreal, then restart the machine; following this I deleted the folders contained in C:\ Users"MyUserName"\AppData\Etc Etc until I found the remnants of the installation files in there. Apparently they don’t get uninstalled and are left there, so the next time I installed Unreal, it pulled those config files (which seems to have been corrupted).

Hope it helps (even if late!)
