Hello! I’ve been having consistent crashes when working in the Unreal Engine 5.1 editor for the past week or so. This just started happening very suddenly. I’ve been working on a multiplayer game in my free time, and I’m working on a character creation screen. The material for the color saturation bar on this screen keeps resetting every time I open the editor, so when I click play and then stop playing, I get an error message. When I close this error log, or any other tab in the editor, the whole editor crashes, and I get the following error report:
I’ve done a ton of research to try to find out what’s wrong, and I heard that I should install the Editor Symbols for Debugging. So I did just that, but it’s still crashing with the same error report. What can I do to fix this issue?
Hello, I’ve had the same issue on 5.0.3 when launching a newly created project. The only working solution I found so far is changing Project Settings → Default RHI from DirectX 12 to DirectX 11 as mentioned by Astrotronic in this forum post: #UE5 CRASH #UE5 Unreal Engine 5 Crash, crash, crash.... Please helpe-me
Hey, thank you so much! As soon as I changed the default RHI to DirectX 11 and started testing things, there were no more crashes! I’ve been messing around in the editor for a few minutes now, and it still hasn’t crashed so far. If it starts crashing again, I’ll leave another comment here, but it seems like the issue has been fixed! Thanks again!
Please note that changing the default RHI to DirectX 11 will disable Nanite. If you are concerned about maintaining access to this core Unreal 5 feature, you should stick with DirectX 12.
That’s a fair point. At this point, UE5 might be stable enough that this crash no longer occurs, but I haven’t tested it. I don’t personally use Nanite much, but if I do, I’ll definitely have to find a different solution for this issue.
It is still happening in 5.4.3. It is asinine. It shouldnt happen at all. These are things that should have been addressed in the developing of the software to begin with.
Nothing that has been suggested has worked for me. I have a pretty beefy laptop and graphics card. Nvidia geforce rtx 2060. Plenty of memory with 64 gb ram and 2 tb of ssd. Ive done everything suggested and unreal still crashes. I can open a new project , then it freezes for a second and crashes. Error 0x000000000028 or something like that. Exception accses violation. Epic games needs to fix this imediately. Stop putting it on the user to figure it out. I have chatted with one guy about it from epic but to no avail.
Greetings. I have a similar bug. Unreal 5.5.3. And to give up Nanite, this is not an option. Found such a dependence. NVIDIA App’s drivers set up a great impact on the failure frequency with this error. I am dropped the settings on the default, and the crush almost stopped.
Ah, right on. I couldn’t tell you the amount of times I’ve had to tinker with my global settings. I understand completely. I’m glad you got it working!
Then there is a separate UI bug with MFAA, when enabled any pop-ups in the editor are buggy looking. It seems like every dialog is rendering the main application window instead of the intended content. The editor doesn’t crash, but it’s certainly unusable.
The NVIDIA control panel has program specific options that you can use to disable these for UE5 if you prefer to leave them enabled globally. I am using a 5090 Suprim SOC Liquid GPU, I have everything else ‘maxed out’ and these are the only options that the Unreal Editor seems to have issues with.
