I also had the same problem with this update and since that pop up would disappear and reappear shortly after changing each web page it also caused problems with selectors with references (anchors).
I solved it by reinstalling the extension as suggested here Edge Browser Popup With "Uipath Started Debugging This Browser" | How To Turn Off - #14 by gheorghestan
The popup is not shown if the extension is installed via group policy. Here are specific instructions on how you can achieve this. Keep in mind, you need admin privileges to be able to install it this way.
In my case the installation path is not as described in the programs folder but in Appdata (per user) and maybe that’s the cause that created the problem, but I simply clicked update when prompted by UiPath (it didn’t ask if per user or as administrator).
