I lost the backup of my Brave wallet phrases!

When I created the Brave wallet as soon as I installed the browser, I saved the 12 keywords in a file and created a password, so strong that even I don’t remember it! As I didn’t have much in my wallet, I don’t want to lose, but I want to make a new one that can receive the rewards! Can I delete this existing one that I can’t get into and create a new one?
