Process running from orchestrator

Whenever I am running the process from orchestrator for first time , I am getting this error “VisualBasicValue: Object reference not set to an instance of an object”.
But from the second time when I am running manually from the orchestrator, I am not getting this error. All the values are getting passed.

@Ritaman_Baral

Is it happening on any specific activity?

can you provide more info

cheers

cannot bring the target application in the foreground. the action was blocked by the current foreground window ‘new notification’ from the process ‘shellexperiencehost.exe.’ getting this error
