**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.
