AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure)

Hello. I’ve been trying to compile a project for a job (my first job requiring this or any intermediate to advanced blueprint coding. I’m a level designer and 3D modeler) and I’m getting this error:

COMPILE_TEST.log (259.9 KB)

Error starts at line 1348.

I was having problems with the Visual Studio and compiler versions but I managed to fix it by installing the recommended versions based on Unreal’s docs on Visual Studio.

LINK TO THAT DOC >>> (Setting Up Visual Studio Development Environment for C++ Projects in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community)

Now I’m facing this problem. I don’t know what it might be, it occured on an empty Third Person project so there’s no extra plugins or settings changed. same error occuring on different projects.

My computer had a windows crash about a month ago and I had to clean install Windows. (went from Windows 10 to Windows 11)
I was able to compile blank projects on Windows 10 but not in Windows 11, I believe it might be due to some setting not being enabled in my computer but the log doesn’t say anything clear about it.(different from when the VS version was 14.40 and not 14.38, Log said that I was not using recommended version)

Any help on finding the solution for this will be great.

Thanks in advance,
Nathan Rech

Okay, I fixed it. the solution was… disabling some plugins…? I disabled Bridge, Fab, Cargo (KB3D) and Dash (PolygonFlow) and it compiled the clean project.
