Editor crashing shortly after startup EDIT: Solved with BIOS update

Development Getting Started & Setup
,

This was solved by updating my BIOS, but I’m leaving this here in case it’s useful to anyone else!

Getting a crash shortly after launching the editor (anywhere from 5-20 or so seconds in), both in blank scenes and example content. I’ll include error messages at the bottom.

I’ve updated to the latest Nvidia drivers, both the Studio and the Game Ready drivers, as well as the previous version of the Game Ready Drivers. I’ve also tried every version of unreal from 5.3.2 onward (including 5.6).

Let me know if there’s any additional information or clarification I can provide.
Thanks!

These errors don’t say anything other than it crashed because of a null pointer.

If you can download engine symbols, that will allow unreal to tell you exactly what triggered the crash, what line of code etc.

You can download engine symbols from the epic launcher, click the arrow next to the installed engine, select options, and then Editor symbols and Engine source. Report back when you get more info on the crash.

Thanks for that advice! I’ve updated the original post with the more verbose error reports.

Let me know if there’s any other info I can submit that would be helpful!

The problem seems to be related to DirectX 12 or the GPU driver. If you’re able to switch to DirectX 11 just to see if the crash stops, that way we can rule it out.

You mentioned you already updated your driver, I would try DDU to do a solid clean install of the driver.

You can also verify the installation of the engine in case something is corrupted. In epic launcher, click the arrow near the engine installation and verify.

Delete Derived Data Cache: Sometimes, corrupted cached data can cause crashes
C:\Users\USER\AppData\Local\UnrealEngine

Let me know how it goes.

Replying again just to let you know I was able to solve this!

I had neglected to update my BIOS. I honestly should have thought to do that earlier, but it seems to be working now!

Thanks so much for your help! I’ll update the original post to include the solve.

That’s awesome, glad you got it sorted and thanks for sharing the solution, I would’ve never considered the bios so I’ll add to to my list and I’m sure this will help someone with similar instability issues.

Also would be nice if you can mark your answer as the solution so it’s easier for people to find.

Cheers
