UE 5.3.1 crashes after a couple of minute in editor

Development Getting Started & Setup

Hey guys!

I was working on my level design for about 2-3 weeks. Suddenly from today UE started crashing all the time while I try to work in the editor. It works for about 3-5 minutes max and then crashes.

Sorry for lot’s of text.

First it was this:

I tried solutions from the community from here and here, but nothing helped. Now it shows this:

I’m stuck on it. Please help me figure it out.

I have the same errors and the engine crashes every 3-5 minutes.
It all started when I upgraded my processor, motherboard and RAM. Before that there were no such problems.
I have a 12900k, MSI MAG z690 and Adata 6400 2x32.
I saw in one of the threads that the problem could be in the E-Core.
I tried disabling them through task manager, but it didn’t help me.
Also saw that you need to update the BIOS
Anyway, this is a very strange problem and there is no answer yet. I hope they will fix it in the next version.

It is very likely this is a problem with your system, not with Unreal Engine, and as such, the next version of Unreal Engine can’t contain a “fix.”
Exactly what the problem is, is very hard to say – could be bad signal quality, bad memory or CPU clocking, bad (or mis-matched) drivers for CPU, chipset, or graphics card, bad BIOS, or a bunch of other things.

I’m afraid to get excited early yet, but it looks like the bios update solved my problem. I haven’t had any crashes for half an hour now.

Have you ever had this crash again after update bios ?

Two PC have the same crash in our team, also the same crash stack, and 3~5 min once.

The PC settings:
LogCsvProfiler: Display: Metadata set : platform=“Windows”
LogCsvProfiler: Display: Metadata set : config=“Development”

I had the same issues as you. I buyed a new laptop with the RTX4070.
Really frustrating if the editor crashes all ~5min.

I did a BIOS update which dont help.
Now its running stable, i disabled Virtual Textures, Hardware Raytracing and disabled the E-Cores in BIOS.

Maybe this helps to you.
In 5.4 i also had no crashes, but im not sure, because I ran 5.4 for about an hour.

Thanx everyone for response. For some reason didnt get the notifications.

Unfortunately nothing helped me. I ended up with completely broken procject wich I could open! So I had to rebuild my entire level from scratch! I switched to the 5.2 and from that point I had just a few crashes.

P.S
Also I suspect the problem might be with one of native UE plugins wich at the time was in beta (I think it was a modeling tool, but not really shure). I suspect the plugin since all the problems from my original message occured after I added that plugin to the project.

Anywas! The level is done now! But I have anothe issue, so maybe someone could help me with that!
