URGENT: Unreal crashes when compiling shaders, HELP!

 

Hello,

UE crashes every time I try upload a project or even UE itself.

The last report I got was:



I've tried re-installing both Aximmetry and UE witgh no luck, problem remains. Also tried updating Windows, updating Nvidia Graphics card.. tried everything!

Just to point out that other projects faces the same issue, meaning some I can enter but they crash samely after few minutes. 

Please help, have no idea what to do!

Thanks guys!

Quick update: Just went to th deafultengine.ini and disabled the ray tracing and SkinCach. Then I re-installed the UE, and it seems to be uploading the fikle, however I can't cook it.. I'm reciving this message:

Hello,

by deleting the deafultengine.ini, apparently, that messed with the ConsoleVariables.ini.

That's what's causing the build issue. Unfortunately, I couldn't find any relevant information regarding your issue,  so you better try posting it on Unreal's forum for a potential solution from them.

Best regards,

Hi,

Some may find it useful what beb0pDrive said for the above Unreal issue, so we translated it here:
Hello, I had the same problem, the solution was to downgrade the version of the bios of my pc. My PC is an i9 asus prime z2790 and RTX 4090. Before updating drivers and bios things worked without problems, after the update Unreal began crashing. After trying many things the solution was to downgrade the bios version from 1410 to 1210.

@beb0pDrive: Gracias por compartir su solución con nosotros. Como ésto es un foro inglés, la traducí para los demás por encima para que todos puedan entender.

Warmest regards,
