Hi @Ammaz_Ahmed1

First, change your UiPath Platform URL to remove /orchestrator_/ from the end. For Client ID connections, it should just be:
[https://cloud.uipath.com/hgfhd/DefaultTenant](https://cloud.uipath.com/hgfhd/DefaultTenant)

If you still get that missing DLL error after updating the URL, the update likely corrupted a cached package:

  1. Close Assistant and kill UiPath from Task Manager.
  2. Go to %localappdata%\UiPath and delete the .cache folder.
  3. Restart the UiPath Robot service in services.msc.

If that doesn’t clear it, running a quick Repair on the UiPath installer should replace the missing System.IdentityModel.Tokens.Jwt file.

hey @Ammaz_Ahmed1 ,

This seems to be an incomplete/damaged update for UiPath — Assistant is unable to load System.IdentityModel.Tokens.Jwt, Version=6.34.0.0.

Please try the following:

  1. Quit UiPath Assistant entirely (also kill all UiPath processes using Task Manager).
  2. Click Windows Settings → Apps → Installed apps → UiPath Studio → Modify.
  3. If this doesn’t work, remove UiPath Studio/Assistant and install latest UiPath Studio/Robot installer by UiPath.
  4. Reboot your PC and open Assistant.

I don’t recommend downloading the DLL manually from any external website. A repair/reinstallation process will resolve this issue.

Hi @Ammaz_Ahmed1,

Firstly, clear the Assistant’s local cache as old, cached DLLs from the previous version can conflict with the new ones. Cache can be found under: %LOCALAPPDATA%\UiPath & %APPDATA%\UiPath

If that doesn’t resolve, then try reinstalling the Assistant. Since this maybe an assembly-loading failure when it tries to authenticate the Orchestrator connection, the update likely didn’t fully install or overwrote a dependency incorrectly. Uninstall UiPath Assistant completely, then do a fresh install of the latest version rather than an in-place update.

I hope this helps.

Cheers!

Hi @Ammaz_Ahmed1 ,
Try these steps once:

  1. Repair or reinstall UiPath Robot/Assistant
    • Uninstall UiPath Robot/Assistant.
    • Download the latest installer from your UiPath Automation Cloud tenant.
    • Reinstall and reconnect to Orchestrator.
  2. Clear local UiPath cache
    • Close Assistant.
    • Delete contents from:
      • %localappdata%\UiPath
      • %userprofile%\.nuget\packages (optional)
    • Restart the machine and try again.
  3. Check .NET Runtime
    • Ensure the required .NET Desktop Runtime version for your UiPath release is installed.
    • Reinstall/repair the runtime if needed.
  4. Verify version compatibility
    • Make sure Robot, Assistant, and Studio are on compatible versions.
    • If the issue started immediately after an update, upgrade all components to the latest patch.
  5. Collect logs
    • Click Create Archive in the error window.
    • Review logs in %localappdata%\UiPath\Logs and share them with UiPath Support if the issue persists.

Thanks
