Build number: 2026.0.182

Bug fixes​

  • We fixed an issue where multiple "System.BadImageFormatException: Bad IL format" errors appeared in Event Viewer and Robot logs, making it difficult to identify relevant runtime errors.
  • We fixed an issue where an improperly owned %ProgramData%\UiPath\Shared\proxy.json file was quarantined without a valid replacement. A default file is now created instead. This prevents confusion with legacy XML-based proxy settings, which are ignored.
  • This version brings several performance fixes.
