Engine build failed with RunUAT InstalledEngineBuild.xml with (Error_Unknown)

Hello,

I’ve been trying to compile nvidia’s nvrtx UE4 4.26 branch with this:


Engine\Build\BatchFiles\RunUAT.bat BuildGraph -target="Make Installed Build Win64" -script=Engine/Build/InstalledEngineBuild.xml -clean -set:HostPlatformOnly=true 

It went fine for more than an hour then the build failed with:


UE4BuildException: BUILD FAILED:  failed, retries not enabled:
AutomationTool exiting with ExitCode=1 (Error_Unknown)

It was successful if I built it in VS 2017, but I don’t need that large size, so I thought to use this method instead for reduced space.
I use VS 2017 15.9.33.

Does anyone have any idea how could I fix this problem?

I put my log with this message.
