I have resolved by doing below Steps .

Go to : C:\User\{YourUser}\AppData\Roaming\NuGet and if you find NuGet.Config file then Delete it .

1. Now go to UIPath Studio and Click start.
2. Click Process and you will get New Blank Process.
3. Please select Language and click create and You will get Design Page. Click Manage Package and go to All Packages.
4. Now search for UIPath.Web.Activities and choose install and Click Save .

Restart UIPath and it should work.
