Brave - Synch "internal synch set-up error" & Cant import passwords from CSV or manualy save any

Brave won’t accept synch code, which gives me an “internal synch set-up error” nor can I import passwords via CSV file or even save/manually add a password to save.

In general, nothing is saving, when I login into gmail, or any other website, I won’t stay signed in. No popups for password saving shows.

Steps to Reproduce.
Synch error

  1. Download and install Brave - left it in default valused.
  2. Opened sanch menu and phased 25 word chain passphrase.
  3. Get internal synch et-up error

Password manager - not importing/saving

  1. Open password manager
  2. Select CSV file exported from Brave on other PC
  3. Succes window popup > close it
  4. No passwords
