Have been packaging and deploying multiple times everyday for the last week or so. All of a sudden I get this:
UATHelper: Packaging (Windows (64-bit)): Running AutomationTool...
UATHelper: Packaging (Windows (64-bit)): Parsing command line: [...]
UATHelper: Packaging (Windows (64-bit)): ERROR: Root element is missing.
UATHelper: Packaging (Windows (64-bit)): Failed to initialize UBT
UATHelper: Packaging (Windows (64-bit)): AutomationTool exiting with ExitCode=1 (Error_Unknown)
PackagingResults: Error: Root element is missing.
UATHelper: Packaging (Windows (64-bit)): BUILD FAILED
PackagingResults: Error: Unknown Error
I have tried removing Saved and Intermediate folders, but still the same. Any ideas?
