I am finding that most of the time when the bot breaks is when I receive a pop-up notification from UiPath (see image), as it is supposed to click on a button behind the pop-up and ends up clicking the pop-up and opening the article.
This is for instllation of chrome extension to allow BOT to identify elements in chrome browser.
You enabled notifications from Uipath site and that’s why you are getting this notifications. For this either you have to disable notifications from Uipath as @sawaseem said or you have to check SimulateType or SendWindowMessage options for those activities to continue working without fail.
