So before this Brave would just freeze up and after about 5 seconds it would resume working, sometimes the Quit or Wait screen coming up, based on my input on the screen.
Yesterday there was an update, and now this just closes the window and everything I type in a field (such as this) is of course gone as it crashes.
Running Windows 10 Pro/64bit latest updates
Some basic settings on Brave.
