@demanga,
First, can you please launch Brave and go to brave://crashes and share the crash report IDs with me here so we can take a look at whats going on on our end? Additionally, are you saying that the browser crashes if “there is a ‘j’ in the search bar at any time, in any place?”
That is, if you type “Brave is great!” into the search bar, the browser will be fine but if you type “Brave is just great!”, then the browser will crash?
