This may happen in 2 cases (or 3rd=unknown bug)
1st case - you are using remote desktop (via RDP protocol) to connect the machine, this is long time known bug not yet fixed. If that's the case and you need to use remote connection, please use VNC or TeamViewer instead
2nd case - you have been using the account (synchronization) before repair and that connection is lost after repair. You then created new passwords vault without being using the account in main UI. Then you try to connect to account, which leads to vault migration to the new location, but that location contains passwords vault you have had before repair, thus it fails. If that's the case, then I recommend following procedure:
- Go to settings/passwords
- Export existing passwords to CSV or for any of supported browsers so will not loose them
- Lock vault (if the option is not available - create master password first - guidance is shown in passwords settings
- After passwords are locked there is Remove vault option in top section of settings page
- Remove current vault
- On Dashboard page, please log in to the account
- Once it succeeded, go to Privacy/Passwords, you should have all passwords back and if you have had synchronization enabled it should work again without any other action required
- If your extension is disconnected then in Settings/Passwords you may establish connection hitting reinstall next to browser icon you want to use in Browser integration section
If none of these helps, please contact me via PM, I would like to investigate your case deeply as it must be related to the bug we don't know about yet.
