Building UE 5.4.2 from source: Missing files despite existing paths

Development Getting Started & Setup

I’m encountering build errors while compiling Unreal Engine 5.4.2 from source. The build process fails to open two files, even though the paths seem to exist:

  1. ‘…\Plugins\Experimental\Animation\HierarchyTableBuiltin\Intermediate\Build\Win64\x64\UnrealEditor\Development\HierarchyTableBuiltinUncookedOnly\Module.HierarchyTableBuiltinUncookedOnly.cpp.obj.rsp’

  2. ‘…/Plugins/Developer/Concert/ConcertApp/MultiUserClient/Source/MultiUserClient/Private/Widgets/ActiveSession/Replication/Client/Multi/Columns/AssignProperty/MultiStreamColumns_AssignProperties.cpp’

I’ve already run Setup.bat and GenerateProjectFiles.bat. Has anyone encountered this issue? Any suggestions on how to resolve it or what might be causing these files to be inaccessible during the build process?

Solved - Reran Setup.bat and regenerated project files
