So I updated some of my packages and now there is no longer a search feature in the activities pane. Apparently it is now necessary to use the universal search. UIPath team, please put the activities search back. I use it quite a bit and it is a pain to have to go to the upper right of the IDE every time I want to search for an activity.
Its got it fixed just now. But no need to reinstall the studio. If the Uipath.sytem and Uipath.Uiautomation activity is reinstalled in the manage package then it will work fine.
