When I open a project in Early Access I am able to do all activities with no problem. The latest version however ends up with this Crash Report:
LoginId:ede1eb6c4181de7c660642ac28081dde
EpicAccountId:4fc399d9c3914c0f90df40c6f5139874
Also the logs have this Warning: LogUObjectGlobals: Warning: Failed to find object āClass None.Physicsā
Followed by this error: LogRHI: Error: Breadcrumbs āRHIThreadā
then followed by a ton of āAftermathā errors.
I have experience with both Unity and Unreal Engine and have started to use Unreal Engine due to my work at CoStar and their work with the Cavrnus. It would be great to get this fixed so that I could get the POCs done for my Arch Vis projects.
Any help resolving this would be greatly appreciated.
Thatāsā¦ honestly a sort of alarming call stack to me, at least at first glance. The final part there is part of the Nvidia driver package, not part of Unreal. Which is not a place Iād want to see page fault errors.
That said, a quick search of the net shows that you can get a page fault in nvwgf2umx.dll with system RAM going bad; a number of folks who have that error have tried doing memory tests of both GPU and system RAM and had one or the other fail. (Hopefully the system RAMā¦)
Beyond that, I donāt know if thereās something in Unrealās rendering setup that could cause a crash in the driver layerā¦ but it sure looks like itās handed stuff off to DXGI (and then Direct3D 12, and then the Nvidia drivers) before things go sideways.
As for āif this were my computerāā¦ I would probably first try uninstalling the Nvidia drivers entirely, and then installing them fresh. Just in case the solution is that simple.
I was hoping that there was something I was simply doing wrong. And maybe the difference between the Early Access and the Current version is that it is possible the Full version comes with everything on.
I did notice that with UE 4.7 if I turned on Ray Tracing the editor would become unstable also. I checked and Ray tracing was not turned on for any of my projects with UE5 or 5.0.1.
That is great advice though, I will do a fresh install of the NVIDIA Drivers and will run a reboot full system mem test. If nothing else (cross my fingers), I can at least rule them out. After I do these steps I will update the post with what I find.
Thanks @Packetdancer for pointing that out. I really should have attempted these steps prior to the post.
Due to work, and this being my home machine, I will attempt to update in the next couple of days, or earlier if possible. =-)
Thereās been enough changes between EA and the release version that I would not be surprised if something is different ā potentially significantly so ā in the rendering pipeline.
I would be curious what happens if you make a completely fresh UE5 project and tinker with it for a bit ā does it still crash, or does it stay stable? If the issue is specifically with the project, it might help to narrow it down.
Iād definitely still be a bit concerned by the crash being in the Nvidia drivers rather than Unreal, though. That smacks of some deeper cause than Unreal crashing ā especially since the crash you have doesnāt seem to be universal.
I just attempted a new project and it died within 40 seconds. Something else I am noticing with the release version is that there is this weird flickering going on with the UI components of the engine. This is something else I am not experiencing with the Early Access copy.
The attempt above was done with a blueprint project and then I attempted a C++ project with the same results. I then attempted mobile with scalable performance and that one did not even fully load the editor before a crash occurred with the same crash info.
All attempts of the same type with the Early Access were successful and stable.
I am also not 100% sold that it is definitely the Engine. It just is odd that one version is working when another is not. I also use Blender 3 which is fully stable on this system. Unreal 5 is the only app I am having an issue with keeping open. I wonder if Windows 11 could be part of the issue.
Iām having similar problems and its driving me crazy. Constant crashes. After 5 - 15 minutes.
Sort of seems to be related to Metahumans as I can work the editor fine until I use one. Then within minutes I get a d3d gpu crash.
Iāve tried everything for days now. Updated GPU Drivers. Re-installed Unrealā¦ played with LOD settingsā¦ raytracing on and offā¦ I use a 3090, so I dropped in my sons 2070 for a test and still did the same. Deleted all my metahumans to clear any legacy content and used only pre-setsā¦ still the same.
I get the feeling a lot of people are having these problems from the number of people out there with āFixesā
Cause:
I have found the fix to the issue. The issue is, especially if you have a newer Direct X card and are running Windows 11, the version of Direct X that comes default with the normal installation process.
How I came across the Fix:
I found the fix due to the fact that I have been a long time player of the DDO game. It was loosing players for a while and became a bit dead. I noticed that there were still updates going on so I installed and ran the game. The same issues were coming up when attempting to run that game. The Devs however had a work around that fixes the problem.
Thatās the 4.8 net framework. Install it too.
// End of the important post part.
As @Packetdancer pointed out, the issue is not with the UE 5 editor, however it is with the Direct X Library. These steps cause the UE5.0.1 editor to be stable for me.
It could also be windows 11 switching to the low power intel GPU on a laptop when you open an editor window. Iāve changed it to always use the NVidia GPU and havenāt had a crash since. Only tested it a few minutes so far but worth a try maybe.
Thanks, that fixed it for me for a day but now the ASUS ROG STRIX III is freezing every 5 minutes again when opening an Unreal 5.0.1 project. It did work fine in preview. I think the -d3dll helps too but still crashes sometimes. I canāt see anything in the windows event viewer but I donāt really know what to look for.
The laptop works fine using other apps. Itās definitly Unreal 5 related. I wonder if it has to do with virtual texture usage or with hardware raytracing set to support Lumen. It crashed once the exact moment I set it to use ray tracing for reflections. But then next time it was fine setting it and crashed later. Confusing.
I crash just opening a new VR template project on UE5 at the moment it loads the project and try tro preare Shaders.
Trying your -d3d11 solution is ok by nowā¦ It is āPreparing shadersā and seems to work properly - cross my fingersā¦
I too have this same mistake, UE5 Early Access is stable but the UE5 final blueprint doesnāt are stable.
And this is the setup, if looks like a little bit with that your have.
My setup is.
11 Th Gen IntelĀ® Coreā¢ i5-11400 (Cache 12 M, 2,60GHz til 4,40 GHz)
32 GB RAM.
Aorus Elite Motherbord.
Aorus WaterCooler WaterForce x240
Nvidia GeForce RTX 3060
1TB of Storage.
and same having this amazing setup, iāma having this error, not is only me but many peoples too.
