Sync stopped working in 1.41.100 103.0.5060.134

Description of the issue:
After update I realized that almost everything got erased. I was logged off from all apps like Gmail. Later on I realized that I have no password field option and that because I lost all passwords. They are still on the other devices but the one I updated (Windows 11 PC) is lost.

When I open sync settings non of the option (Sync everything /Customize sync) is selected. When I choose Sync everything it doesn’t save it so when I open setting again non of the option is selected.

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

  1. Update to 1.41.100
  2. Open Sync settings
  3. Change sync settings

Reproduces how often:
Every time

Brave Version(See the About Brave page in the main menu):
1.41.100 103.0.5060.134

Type of devices currently running on the Sync chain in question:
Windows 11 PC

Additional Information:

How many other devices are a part of this Sync chain? Additionally, on those other devices, do you have the Sync everything option enabled there?

I have another MacBook and phone in chain.

MacBook works fine, it syncs everything (setting is correct).
iPhone, on the other hand, all of the sudden left chain (alhtough when I check on PC and MacBook it shows that it stills there) and created new one on its own o_O

So at the begining all 3 devices had sync all enabled and now :
MacBook - no change, working as expected
PC - lost all data and sync, cannot change setting anymore
iPhone - created new sync chain on its onw

So the only device not on the chain and working properly is the PC, correct? If so, can you elaborate a bit on what you mean when you say you “cannot change the setting anymore”? Are you referring to the Leave Sync chain option?

Yes, the only affected device is the PC, that’s correct.

Please check the screenshot below. This is what I see everytime I open “Sync” options. Nothing is checked. Even when I check some option like “Sync everything”, once I close the window and open a settings again , I see the same screen with non of the option selected (No “Sync everything” nor “Customize sync” )
