@nancy.gandhi what UIAutomation.Activities package version are u using? Can you please share an excerpt of the failing workflow? Thank you

@nancy.gandhi this looks like a Dependencies issue. Can you share a screenshot of your project dependencies with the UIAutomation.Activities dependencies expanded? Something like
