Even to me it happened that this command remains locked and does not go on, depends on the loading of the page, if the page does not load in a short time kantu stops. I have had some freeze cases with this command but it depends on the page load and Kantu waiting for the page to be loaded to execute subsequent commands.
Does not always occur because it depends on the detection of the loading of the page by Kantu, usually after this error shows that Kantu is not connected to the tab, in this case you must open a new tab load a valid URL and restart macro
