UE5.X crashing when >3 windows are open

Hello friends! I am asking for help with a problem that I have not been able to solve for six months now.
When I`m open three or more windows inside Unreal Engine ( e.g. Anim BP, Actor BP, Material Editor etc.) he is permanently crashed. It occurs only in UE5.x. (in 4.27 all is OK)
This is not a RAM or video RAM problem because UE crashes when there is still a lot of free memory left )

How to find out the cause of this crash? Can I use specific analysing software? Please help!

OS: Windows 11

You should only have 1 instance of the editor open or you risk corrupting your project. If you want to test out multiplayer then either pack the project (and run 3 instances of it) or set the player count to 3 in the editor

I apologize for the misunderstanding. I meant 3 open windows inside editor e.g. Anim BP, Actor BP, Material Editor etc.

Does your computer meet the requirements for unreal 5? The requirements are a lot larger than unreal 4.

Yes. I have a relatively modern hardware:

CPU OctalCore , 4900 MHz (49 x 100)
MB ASUSTeK COMPUTER INC. PRIME Z590-P
RAM 32608 МБ (DDR4 SDRAM)
GPU NVIDIA GeForce RTX 3070 (8 Gb)

I’m not seeing any specific errors related to crashing.

Only thing that is visible in the xml file is the line

<ErrorMessage>Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000018c04</ErrorMessage>

So it could be a memory issue. Have you ever used other programs that would hit your memory limit near it’s maximum (blender, maya, 3dsmax), if so were they stable at that time?

You could try running memory testing. In windows “Windows Memory Diagnostic” to do a full scan of your memory.

If your memory is getting full with 5.x then maybe increasing your pagefile size could help.

If it’s a hardware issue then you’d need to check each ram stick separately and find the problematic one and replace it.

The crash doesn’t seem normal. You could also try the studio drivers from nvidia but I’m not seeing specific GPU errors in the logs.

Thank you for your reply.

Yes, only UE5 is crashing.
I’ve already installed the studio driver. no success.
At first I thought it was a memory problem too. I checked the memory with TestMem5 and there are no errors.
I will try to check each ram stick separately.

I`ve checked each ram stick separately. No Errors. UE 5.X still crashes (
Maybe there is such software that can more accurately identify the cause of the application crashing?

Have you tried re-installing the editor in a new location? I would try uninstalling Unreal, restarting the computer, and then install again, but to a different directory. If you’re not using the default directory with the first install, then do so for the re-install, or vice versa.

OMG Thank you! After reinstall UE5 to the new location the problem witha a crash is solved!

Glad that worked. Maybe it was an issue with Virtual memory or something on the HD you installed it to. I’m curious if you installed it to another drive or just a different directory on the same drive?
