UE-R5 Fatal Error when on the Brethren Brig

[versed oyster]

My game has been crashing from time to time while just playing the game, most of the times it takes 1 to 2 hours to crash. But whenever I get on a Brethren Brig, my game crashes within 5 to 10 seconds consistently. I've built one and can't use it because I can't even get to move it before the game crashes. I will add a few logs here.

Some of these logs are from just playing the game, others are from getting on a Brethren Brig.

I've tried all the solutions on the FAQ page while also trying some things a few other people said here in the discord like the '-d3d12 -norhithread -nothreadtimeout' launch options.

Thanks for the report. Have you tried verifying your game installation?
What are your PC specs?

I can try verifying the game installation and return the result for you. It is easy to test since I can just board the ship and see if it crashes. It usually crashes almost instantly.

It still crashed.

[blissful grove]

Understood, we'll look into it.

[versed oyster]

Thanks! I will be waiting for any return.

Is there any possibility of the game supporting DX11? I think that would solve the problem for a lot of people.

I got the crashes both when playing multiplayer and offline.

But I have a update. Through many tries (and many crashes) and with the help of AI to understand the logs better, I was able to find out what was crashing the game for me. It's the Nanite. I had to disable it in the Engine.ini (r.Nanite=0) along with Virtual Shadows and Lumen.

The cost is that most assets like workbenches and island structures look super low-poly or broken like in the screenshot.

But after that, I can play without a single crash, even on the Brethren Brig.

I've put some commands on the Engine.ini (like the r.Nanite=0) and changed the file to read-only, so the game doesn't delete everything that I wrote there.

Also, I had to change Global Illumination to Medium at minimum. If I have it at Low, the game looks like this.

This is how my Engine.ini looks like:

[GameNetDriver StatelessConnectHandlerComponent]
CachedClientID=47

[/Script/Engine.RendererSettings]
r.Nanite=0
r.DynamicGlobalIlluminationMethod=0
r.ReflectionMethod=0
r.Shadow.Virtual.Enable=0
r.Shadow.AutoPrimitiveMerge=0
r.DistanceFieldShadowing=0
r.AmbientOcclusionLevels=0
r.ForceLOD=0
r.StaticMesh.MinLOD=0
r.LODDistanceScale=2.0
r.StaticMeshLODDistanceScale=0.1
r.ViewDistanceScale=1.0
r.MaxPolyCountPerFrame=2000000

[TextureStreaming]
r.Streaming.PoolSize=3500
r.Streaming.LimitPoolSizeToVRAM=1```

I hope that this somehow helps anyone with the same problem as me and the devs.

I really liked the game, so I'll bear with the low-poly structures to be able to keep playing the game without crashing constantly.

Yesss I have received that error a few times as well!
No chugging, stuttering or lagging issues. Just BOOM.

Thanks for sharing. I’m having the exact same crash. I tried your fix and copied everything into the file, but unfortunately I still get the same crash. Also, the devs haven’t provided any update yet, and they haven’t replied to my post for 2 days. This issue has been happening since launch.

[versed oyster]

Sad to read that it didn't help you. Yeah, I also got no updates from them, I just hope that despite having no answer, they are working on these issues. Sadly, it looks like this crash despite being the same error, it comes for different reasons. In my case, it looks like my GTX 1080 can't handle de Nanite technology used on UE 5.6, so, turning it off did the trick. But I also a lot of people that use AMD having this error, but it probably is because of another reason.

I've posted my crash log here in hopes to get some answers about what was happening, but what actually helped me understand my logs was using AI. Sending my logs to an AI made it give me solutions, I kept trying the solutions and sending the logs every time the game crashed until the AI found the answer to it.

Yeah, I get what you mean. I’m on an RTX 2070 Super and I already have most of these settings low or disabled. I’ve also tried pretty much everything I could find on the internet, but nothing really changed for me. It feels like the same crash but maybe caused by different things depending on the system. I just wish the devs would at least acknowledge it or give some info, because right now we’re just guessing.
