Random sync failure AND being logged out of numerous websites for no apparent reasons. Major problem

Description of the issue:
Very random, very intermittent but a big inconvenience when it happens. Sometimes after reboots (probably after Windows updates), when I open Brave it loses all my login sessions for things like social media and email and everything else.

Also my device gets kicked out of the sync chain without warning as well. I am pretty sure this is a very common longstanding open issue but I can’t seem to find the link for the Github Issue for this.

Steps to Reproduce (add as many as necessary): 1. 2. 3.
Impossibly difficult to reproduce because it is very intermittent BUT I do know the issue persists after a fresh install ON a different laptop WITH a different install method (new one I used the official installer from the site and old one I used winget.) I cannot reproduce at will but can limit it down to fewer stuff as follows (if memory serves me right.):

  • Issue persists (albeit very randomly) after a fresh install of latest Win 11 on an unrelated laptop.
  • For my previous laptop, Brave was installed with winget but on this fresh install it was installed via the official downloaded installer. It worked fine then one day out of nowhere it did it again for no apparent reason.
  • When the issue happens my device ALSO gets kicked out of the Sync chain and I need to re-add my browser to the sync chain again. On my old laptop this DID NOT work because it just says something along the lines of “Internal Sync error” or something… Can’t reproduce now because it is so intermittent. On the newer one though, I can re-sync it okay… Not sure why.

Actual Result (gifs and screenshots are welcome!):
Browser opens seemingly normal but then when I go to my email and other social media accounts I need to log in again. Also under brave://settings/braveSync/setup it prompts me to do the “Sync Setup” again which is annoying to say the least.

NOT A SINGLE ONE of my log-in sessions persisted so I needed to log back into all of them.

Reproduces how often:
Very randomly.

Operating System and Brave Version(See the About Brave page in the main menu):
Brave 1.79.126 (Official Build) (64-bit)
Chromium: 137.0.7151.119

Additional Information:
Sync randomly failing and needing to be set up again is really annoying but the major dealbreaker is login sessions randomly not persisting for all my accounts.
The latter is just unacceptable so I will go back to my old browser for now until the foreseeable future.

This is really becoming a problem. My brave on linux loses randomly all logins, or gets “kicked” from the sync chain somehow. It happens a couple of times per month.

All sorts of sync issues. It’s the exact reason I left Vivaldi, they had the exact same problems and it is simply not possible to use the software in this state.
