Hi,
i am trying to build unreal engine 5.4 from source, i followed the documentation step by step (from this link Downloading Unreal Engine Source Code | Unreal Engine 5.4 Documentation | Epic Developer Community).
When it is time to build UE5 (after downloading visual studio 2022, downloading ue5-release from github, running setup.bat, running generateprojectfiles.bat, i open ue5.sln in visual studio and right-click → build) it opens a command prompt window, starts to build, then says theres 6000+ things to compile which is normal, but between the 40th and the 80th element to compile my pc just completely freezes (sometimes it even just restarts without warning!!), and there is nothing i can do from there.
For info these are the specs of my pc (brand new):
Motherboard: ASUS Prime Z790-P WiFi Gaming
CPU: Intel® Core™ i9 14900KF
GPU: NVIDIA® GeForce RTX™ 4090
RAM: Corsair DOMINATOR 2x32Gb
SSD: 2 x M2 NVME 2To
Watercooling: NZXT Kraken RGB BLACK
Pc is not overclocked
At first when the pc freeze i thought i should just let it work for a while (maybe it was still building in background) but given the high end components of my pc i assumed this was not normal so the only thing i could do is force shutdown and restart…
Since then i did not manage to prevent my pc from freezing while building, i also already tried these options if you thought it could be a solution:
- restart my pc
- Update Windows and Visual Studio
- re-download the source code
- re-download visual studio
- Rebuild the project (clean+build)
- Limit the cpu power consumption in the BiOS (from unlimited to 500A)
- Moving the source code in a different location
- Stress test the cpu, gpu and ram → everything ok
- Check overheating/Throttling → everything ok
- Check the windows log file (empty)
- Check the UnrealBuildTool log file: see end of message for complete log output
None of these options worked (after searching on forums, websites, asking chatgpt) so I come here to create this new post in hope that someone can save me from this never-lasting problem…
(I just bought the pc precisely for my UE5 project, building unreal from source is the very first thing i did come on man help)
Part of the Unreal Log.txt file in Engine\Program\UnrealBuildTool\ folder:
(some of it is in french, i put it here because there is a compilation error saying the build will fail…)

And here is a screenshot of the output log just before it crashed (i did a screenshot because there was a fatal error)
Thanks in advance for those reading my message, hope you will have a better day than mine…
