How to resolve could not start executor. Unable to find an entry point named 'StartProcessUsingToken' in DLL 'UiPath.Session.dll'

  1. Close all UiPath processes (Studio and Robot).
    2. Stop the UiPath Robot Service (services.msc -> UiPath Robot -> Right click + Stop)

    3. Search for UiPath.Session.dll file in the Studio installation directory (C:\Program Files (x86)\UiPath\Studio)
    4. If there are multiple files here, remove the oldest one.
