Hi @abdel

Can you check the extension of the edge browser is enable.

If the extension is already enable. you remove the extension and try it.

Add via in uipath → Home → Tools → enable the edge extension



First try upgrading the system package and give a try
Go to design tab in studio → manage packages → project dependencies → upgrade system.package and UIAutomation.Package and try running the bot


Try the same with INTERNET EXPLORER as it doesn’t need any extension
This will help you even if your browser extension is not working or couldn’t install the browser extension


If u are allowed to install browser extension in your machine then go to Studio → Home → Tools → and install the browser extension of the browser application you are using

Hope this would help you resolve this

Cheers @abdel

Make sure you have the latest edge browser version and try again after restarting the machine
