Hello everyone,
I’m encountering a persistent issue while attempting to migrate my project to Unreal Engine 5.5. The build process consistently fails with the following error in Visual Studio:
The command "C:\UE5\UE_5.5\Engine\Build\BatchFiles\Build.bat SwimmingPooEditor Win64 Development -Project="C:\Sp\SwimmingPoo.uproject" -WaitMutex -FromMsBuild -architecture=x64" exited with code 6.
Here’s what I’ve done so far to troubleshoot and try resolving this issue:
Checked Folder Permissions:
- Verified that the mine project folder is not marked as "Read-Only.
- OBJ folder in UE5.5 folder I also made to be writable
Ran Visual Studio as Administrator:
No changes were observed in the behavior of the error.
Updated Tools:
Made sure Visual Studio and all project-related tools and plugins are up to date.
I tried also opening the project in the same way on 5.4.4 and it works correctly without almost any problems
Inspected Build Settings:
Ensured that the target build settings (Win64, Development) align with the project’s requirements.
Despite these efforts, the error persists, and I am unable to progress with the project build.
The error log in Visual Studio does not provide much additional detail beyond the error code.
I would greatly appreciate any insights or suggestions on what might be causing this issue. If anyone has encountered a similar problem or has ideas for further troubleshooting steps, please let me know!
I’m Technical Artist and don’t know the c++, and our programmist leave the project so I need to hustle 
Thank you for your support.
