UiPath is not responding after copy action
When i try to copy any activity, studio entering non responding state for a couple second and after that let you to paste what was copied.
Cleaning of the packages solved the issue
Navigate to below
It would look something like below, delete everything.
In case if it doesn’t allow to delete something , reboot the system and than try deleting.
Now when you open studio for the first time, the core packages will be downloaded automatically and thereafter other related dependencies.
