Macro Output Error

Hi, I tried running one of my RPA files , it used to work and now it keeps giving this error :

Could not find member ‘MacroOutput’ in type ‘http://schemas.uipath.com/workflow/activities:ExecuteMacro’. Row: 298, Column: 85

Any idea what could be the issue?

Thanks

This kind of error can be caused, when you try to run project on different version of UiPath. For example, some of the options of the activities can be changed, and not accessible anymore.
