Hi @farhanliaqat,  
Make “json” file backup and remove it from project. Then open it from main.xaml and import every needed packages used in the project. The new json file should be automatically generated. Hope this will help 🙂

Hi @farhanliaqat

I had a quick search and it seems to be related to either nuget packages and/or netframework:

> **[Visual Studio Feedback](https://developercommunity.visualstudio.com/content/problem/557810/error-occurred-while-restoring-nuget-packages-foun.html)**
>
> Visual Studio Feedback

I would suggest first to try and clear these two folders:

```auto
%userprofile%\AppData\Local\UiPath\.cache
%userprofile%\.nuget\packages

```

Feel free to backup both folders beforehand.
