Bookmarks sync completely destabilized Brave - awful!

windows
#1

Description of the issue:

Brave becomes unresponsive after enabling Sync. Deleted all bookmarks, but they keep coming back. Impossible to re-stabilize Brave - unusable.

Steps to Reproduce (add as many as necessary): 1. 2. 3.

  • Enabled Sync with ONE iOS mobile device.
  • iOS mobile device never synced - Brave froze and had to kill/restart app.
  • On the PC side, nightmare followed with the following issues:
  1. Brave becomes unresponsive, consuming 500MB+ of RAM and lots of CPU.
  2. Originally had 1500+ bookmarks, which I was able to export and then deleted.
  3. Bookmarks (unsure which ones - seems pretty random, different each time) keep coming back!
  4. I’ve deleted bookmarks over and over again, still come back.
  5. Impossible to stop and re-stabilize Brave no matter what I try.
  • Disabled sync on both devices.
  • Problem continues on PC side. Mobile device appears okay.

Actual Result (gifs and screenshots are welcome!):

Brave becomes unresponsive on PC, and bookmarks keep coming back after deleting them.

Expected result:

Brave works.

Reproduces how often:

Persistent issue.

Operating System and Brave Version(See the About Brave page in the main menu):

Version 0.62.51 Chromium: 73.0.3683.103 (Official Build) (64-bit)

Additional Information:

Since I saved the bookmarks, I’d like to completely reset/stabilize Brave. What’s the best way to do so? Is there a way to save my extensions configuration and then completely NUKE every last bit of Brave and re-install? I don’t want to deal with this instability. I want to start fresh (and be able to restore my configuration - even if I have to do so manually to ensure I don’t carry over any of this damage - this is a nightmare).
