Hi @thigalekajal,

To resolve this issue, try uninstalling and then reinstalling UiPath Studio. Reinstalling often resolves version mismatch issues and fixes corrupted or missing components.

Additionally, ensure that the UIAutomation package is updated to the latest stable version in your project. Keeping the package up to date helps avoid compatibility issues and ensures you have the latest fixes and improvements.

Hi Gorby,

Thank you for asking. I resolved the issue by reinstalling and updating the UiPath Chrome extension, and then restarting UiPath Studio and the browser. After ensuring the browser and UiPath extension were compatible, the communication issue was resolved.

Thank you again for your interest and support.

Sure. I’m using UiPath Studio 2026.0.197 STS and the UiPath Chrome Extension version compatible with this Studio release.
