Update to keychain and Windows error makes key sync impossible

First I tried submitting a direct request at the help center here: https://support.brave.app/hc/en-us/requests/new?ticket_form_id=36973599432845
The Issue section is greyed out. So, it can’t be submitted to Zendesk.

I’ve had the same account for years with my bookmarks in my account. When I enter my old keys to my sync, Brave said they aren’t working anymore. They said they are obsolete when I try to use them. I need to get keys back. When I bought my new computer in April of 2025, they were working. After my OS and update crashed last week, they don’t come back up. When I enter the sync code, I get an error about the version.

I downloaded the old Brave stable from when I started back in 2020, Version 1.82.157 (brave-v1.82.157-win32-x64.zip) from GitHub.

When I opened the old Brave, it just closed itself. I couldn’t even open the sync settings.

I do still have a nearly everything from my profile before the crash like my app data folder. I do have my internet history that I’ve been keeping. It could be possible to assemble a lot of my old bookmarks, but it would probably take me another week to set it up. When I open the app data folder for Last Version, it says 150.1.92.141. Is there a file I can send to recover it? I also started my account with my old school email. I had a small amount in my wallet from ads.

Alright, so as I was writing this, I figured out how to get my bookmarks back. It was in \AppData\Local\BraveSoftware\Brave-Browser\User Data\Default. I have my bookmarks, but I still need my keys. I found my extensions in the folder with manifest files in the name:. It is taking a while though.

Is there a file I can give you or do I have to start from scratch? I can give you a file and also verify my email address.

How do I get my keys back?
