Google accounts just randomly become signed out

Description of the issue: Just randomly signed out of both my accounts since the latest updates to defeat YouTube. It doesn’t happen when I close the browser or mess with the settings. It just happens suddenly and randomly, even while I’m in the middle of working.
Only signs me out of Google, stays signed in on YouTube and all other websites.
I’ve got Brave Shields turned off for Google’s search engine and the accounts page, but it’s still happening.

How can this issue be reproduced?

  1. Using Brave normally.

Expected result: Staying signed in on Google accounts.

Brave Version( check About Brave): v1.82.166

Additional Information: The only other extension I’m running is uBlock Origin, and I have the “I don’t care about cookies“ list enabled. But I’ve never had issues with that before.

This is a known issue that the team is working on addressing presently:

The problem is that my accounts are getting logged out not after I close my browser, but right in the middle of a session. I can literally open a Gemini tab and have no chat history on the left side, which means I’ve been logged out.

@DeepDarkQuantum closing this as there are too many duplicate topics open. Current Github on this is at https://github.com/brave/brave-browser/issues/49300

Long story short, they have been trying to figure this out and are hoping to get solutions for people experiencing the issue soon.
