Hi community,

I have been having issues with a package that I want to upload to my orchestrator. It is currently functioning well in production, but I want to make a small adjustment to it. However, when I do, it gets stuck in Studio with the message box which says “Compiling Activities”.

If I cancel it, I can see that the last message I get is the following:
COMPILER: Starting xaml documents compilation

Anyone know the solution to this issue? Thanks!

Hello @henry.wang, try some of these steps:

  1. Restart Studio: Sometimes, Studio might have encountered an issue that can be resolved simply by restarting the application. Close Studio and reopen it.
  2. Check Dependencies: Ensure that all dependencies and packages in your project are up-to-date. Outdated or incompatible packages can sometimes cause compilation issues. Use the “Manage Packages” feature in Studio to update or reinstall packages.
  3. Clear Temporary Files: Clear the temporary files used by Studio. Navigate to %userprofile%\AppData\Local\Temp and delete the contents of the “NuGetScratch” folder and any UiPath-related folders.
  4. Check XAML Files: Review the XAML files in your project for any errors or issues. Check if there are any unresolved variables, arguments, or activities.
  5. Disable Parallel Execution: In some cases, enabling parallel execution might lead to compilation issues. You can try disabling parallel execution in the Studio settings:
  • Go to “Tools” > “Options.”
  • Under “Design,” uncheck the option “Enable parallel execution of workflows.”
  1. Update Studio: Ensure that you are using the latest version of UiPath Studio. Sometimes, updating to the latest version can resolve compatibility issues.
  2. Check for Conflicts: If you have custom activities or dependencies, ensure that there are no conflicts between them and the activities in your project. Sometimes, conflicting custom activities can cause compilation problems.
  3. Check Project Settings: Review the project settings in Studio to ensure they are configured correctly. Pay attention to the target .NET framework and other project settings.
  4. Check Antivirus/Firewall: Antivirus or firewall software might sometimes interfere with Studio’s operation. Temporarily disable or configure your security software to allow Studio.
  5. Reinstall UiPath: If all else fails, consider reinstalling UiPath Studio. This can help resolve any corrupted installations or settings.
