  • Upgrade the Studio to 2021.10.8 or 2022.4.4 as your Studio version is not supported anymore by UiPath.
  • Add only these external package sources in C:\Program Files\UiPath\Studio\NuGet.config
  <packageSources>
    <!-- Add this repository to the list of available repositories -->
    <add key="Local" value="C:\Program Files\UiPath\Studio\Packages\" />
    <!--  <add key="Local" value="C:\local feed path\" /> -->
    <add key="Marketplace" value="https://www.myget.org/F/workflow/api/v3/index.json" />
    <add key="Connect" value="https://gallery.uipath.com/api/v2" />
    <add key="Official" value="https://packages.uipath.com/activities" />
    <add key="nugetorg" value="https://api.nuget.org/v3/index.json" />
</packageSources>
