Hi 
I am not able to package my project because of this annoying cooking error:
UATHelper: Packaging (Windows (64-bit)): ERROR: Cook failed.
UATHelper: Packaging (Windows (64-bit)): (see C:\Users\ADO\AppData\Roaming\Unreal Engine\AutomationTool\Logs\C+Program+Files+Epic+Games+UE_4.25\Log.txt for full exception trace)
UATHelper: Packaging (Windows (64-bit)): AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure)
UATHelper: Packaging (Windows (64-bit)): BUILD FAILED
PackagingResults: Error: Unknown Cook Failure
And then this writes:
LogD3D11RHI: Warning: NvAPI_Disp_HdrColorControl returned NVAPI_NOT_SUPPORTED (ffffff98)
