This is how we need to handle with this error buddy @tomato25
so finally it implies that go to package manager in design menu and install all the packages that were missing @tomato25, and here it is UiPath.Core.Activities
If already installed, upgrade them to your studio version buddy @tomato25
and the reason why you were not able to see images is the screenshot folder might not be there along with project folder, thats why we are missing with images…
Kindly try this and let know whether you were able to get the activity
Cheers
