UiPath Forms not loading

Robott · January 13, 2023, 8:12am

Hi, i am facing problem with UiPath.Forms activity. It was working but suddenly it is not totally blank in studio and assistant also. It just won’t load anything in Form Designer. I uninstalled the activity and installed it again but no difference at all.
It is not showing any error also.
what changed recently is: i changed the .nuget folder path from standard to out of Drive C. It started loading packages in the new .nuget folder
Not sure if it has something to do with that.

What could be the reason behind this?
