Urgent: Validation Error in invoked workflow

[nadim.warsi]

Can you try the below?

“go to %localappdata\Temp\nuget% and check if you have two folders/versions of Newtonsoft.Json? For example it could be one with 8.0.3 and one with 10.0.3. Remove the one with 10.0.3(you can copy it in some other place) and check again”

Other than %localappdata%\Temp, try to see if you have the 10.0.3 version of Newtonsoft in other places, like: C:\Program Files (x86)\UiPath\Studio\Packages %localappdata%\UiPath\Activities %localappdata%\NuGet\Cache Folders of other custom activities that you downloaded or created
