UiPath errors / Version

Could not load file or assembly 'UiPath.System.Activities, Version=23.4.2.0'

platform: UiPath / category: Version / versions: 23.4.0

Cause

Studio 23.4.0 had a packaging defect where published .nupkg files listed incorrect runtime dependencies in the .nuspec, so the Robot fails to resolve UiPath.System.Activities at execution.

Fix

Downgrade Studio to 22.10.7 and republish. Or extract the .nupkg, correct the .nuspec dependency entries to the 22.10.7 format, repack, and re-upload. Add the UiPath Official NuGet feed to NuGet.config so the Robot can resolve packages. Upgrade past 23.4.0 once verified.
