Instant Crashing on macOS

I showed my girlfriend that, on Brave, you can even block ads on sites that block you from their content unless you white-list them from your adblock. This convinced her to get it, but that wasn’t the case for her. I realized that I was actually running the beta build and thought perhaps it was a beta feature, so I told her to get the beta build. Unfortunately though, the beta build just crashes before even loading a window. She’s on macOS 10.14.5.
