Hello, i try package my game for iOS and get this error:

System.Exception: A conflicting instance of AutomationTool is already running.

LogPlayLevel: Error: ERROR: System.Exception: A conflicting instance of AutomationTool is already running. Current location: /Volumes/DataFiles/Unreal_Engine/UE_5.0/Engine/Binaries/DotNET/AutomationTool/AutomationTool.dll. A process manager may be used to determine the conflicting process and what tool may have launched it
LogPlayLevel: Error: ERROR: Stage Failed. Missing receipt '/Volumes/DataFiles/_PROJECTS/UE_Projects/LightnerComplete/Lightner/Binaries/IOS/Lightner.target'. Check that this target has been built.
LogPlayLevel: Error: RunUAT ERROR: AutomationTool was unable to run successfully. Exited with code: 103
PackagingResults: Error: Launch failed! Missing UnrealGame binary.
You may have to build the UE project with your IDE. Alternatively, build using UnrealBuildTool with the commandline:
UnrealGame <Platform> <Configuration

Somebody know how can i fix it?

@VOXELIUM
Since one is already running, it may be visible in your Task Manager. You could stop its processes, and then try to start building again.
Which Unreal version are you using? If that doesn’t work, you may need to try the command line prompt provided to force a build.
Let me know if this works!

I found that this patch to UnrealBuildTool fixed up the situation when this kind of error occurs. [UBT Bug] No longer able to compile plugins in standalone since 5.3 - #11 by Sam_Swain Hope that helps.
