Sync chain data won't load any more

Description of the issue:
My Sync chain won’t load any more… The 25 code is right and when I enter the codes in sync section. It doesnt give me an error or anything it just freezes on pc without loading the devices on the device list (and the other info)… on Android, it wont load anything also… The problem is that; I dont have any active devices on the sync chain right now but I have the 25 codes and I changed the 25th code with the daily code. The code is right but the sync chain seems broken or something

Ive tried different devices including android and pc. And I also tried different versions of brave browser. I also tried vpn . The sync chain wont load at all.

Brave Version(See the About Brave page in the main menu): android v1.66.120
