Hi
First, I suggest you install Firefox and import your bookmarks and logins as *.CSV; Keep the file in a safe place. You can import it to Brave in case there is a problem.
Second, try the following (in this order) and see if you can copy, export your passwords.
- Disable extensions
- Reset Flags at
brave://flags/(if you haven’t enabled or disabled features before). - Login without fingerprint
- Reinstall (update) Brave from Release Channel 1.41.100 (Click on Download Brave Browser)
