Launch New Browser Action will not connect to the browser

Power Automate Desktop was updated last week and since then the Launch New "Browser" action has not been able to connect to the chosen browser. This is the error message I am getting: "Failed to assume control of Microsoft Edge (Communication with browser failed. Try reloading extension)."


Error Details: "Exception of type 'Microsoft.Flow.RPA.Desktop.UIAutomation.WebAutomation.Core.Browser.WebBrowserException' was thrown.: Microsoft.Flow.RPA.Desktop.Robin.SDK.ActionException: Failed to assume control of Microsoft Edge (Communication with browser failed.

I have tried a variety of ways to fix this (such as redownloading the Extention) and have come up with nothing.

I had to switch browsers from Microsoft Edge.

I have had the same problem with Microsoft Edge since I updated PAD to the last version (2.15)

I tried enabling/disabling the extension, rebooting the computer, reinstalling Microsoft Edge, but still is not working ...

I have another computer with the same PAD version and it is working fine, so I don't understand

Did you find any solution?
