The only thing I can think of that would be causing this at this time is removing the device from a Sync chain (which you did and didn’t resolve) or potentially a particular extension you have installed is causing conflict, but if that were the case then the Guest window should not have crashed.
Since the Beta is working (for now at least), this points to an issue isolated to the Stable installation rather than Brave and your system. If you’ve already cleared your cache and browsing data, you may want to try an un/reinstall of stable and see what that shakes loose.
I know that’s not ideal, but you can export your bookmarks, as well as passwords as
CSV files (respectively) reimport them into the fresh installation.
- Exporting Bookmarks is fairly straightforward
- You can export passwords in
Settings --> Autofill --> Passwords but to import them, you’ll need to flip a flag to enable this functionality. Type
brave://flags into the address bar and search for the
#password-import flag. Enable it and relaunch when prompted. You’ll now have the option to Import passwords (in same menu as export).
Let me know what you find out.
