Hey there,

Thanks for reporting this. A quick test that you could run is recompiling/obtaining the binaries from UE5 main ( **//UE5/Main/Engine/Binaries/Win64/UnrealBuildAccelerator/x64/** ) as we did have some issues for 5.6 (and are preparing for 5.6.1). If this also fails in your setup, would it be possible for you to try this again in debug, and provide the logs. The process is outlined [here](https://dev.epicgames.com/community/learning/knowledge-base/jB32/unreal-engine-practical-debugging-tips-for-unreal-build-accelerator).

Kind regards,

Julian
