Hi, I’m experiencing repeated crashes in UE 5.1.1
The crash happened first in editor when I tried to reimport a mesh from a new file. This now happens with most meshes on import or transform. I did import a cube with no immediate crash. The problem applies to my scene and also a new scene created with the Third Party Template in 5.1.1. I tested a scene in 5.0.3 and did not experience the crash.
I appreciate help figuring this one out.

Error following transform, delete, and sometimes navigating the scene.
Hey there @tea-hot! Welcome back to the community!
This references a graphics DLL most of the time, and since it’s functioning in 5.0.3 and not in 5.1.1 it’s safe to assume this may be an issue between the GPU drivers and DX12/Sm6.6.
Since you’d already swapped down to studio drivers, I don’t have to reference that they are regularly more stable. You’d also already reset the GPU settings, and cleared the cache so that’s good.
A couple questions/things to try:
Quick double check the drivers are up to date.
What Anti-Aliasing are you using for the project? Try swapping that around in the Project Settings (or just setting it to none) and seeing how everything runs.
Does swapping down to DX11 relieve it? (This can help verify the issue and also be a temporary workaround)
One user that had a particularly resistant issue like this solved it:
Another batch of possible workarounds/solutions from a previous thread:
Hello SupportiveEntity, thank you for the in-depth response. It’s very much appreciated.
I think I fixed the problem. *** EDIT this may have helped but not fixed the problem ***
My Manual Auto Complete List Index Command did not match my default RHI. Since that setting is at the engine/platform level it affected everything…ouch.
Dropping to DX11 is more of a workaround to keep working in the meantime, as the environmental issue causing the crash is still present. I’d say definitely try to update the drivers (maybe a fresh install incase there were corrupted portions). After that, definitely try out Graeme’s solution, as that’s solved it for a few users (while being annoying if you use their game ready drivers but if you’re on studio already shouldn’t be too big of a deal). Let me know how it goes!
