My Windows 10 computer and Android would not sync. I could not see the devices when I viewed Settings/sync. When I selected “Leave sync” on either device nothing would happen or the browser would crash. I am using v1.43.89 on my Windows to device and **v1.43.90 on my Android device.
Error: GenerateCryptoErrorsForTypes@components\sync\driver\data_type_manager_impl.cc:33, cryptographer error was encountered. Errors can be found at Brave://sync-internals.
I resolved the problem in Brave://sync-internals by selecting “Disable sync(delete data)” on both devices. After deleting the old sync data your devices should be free to start a new sync chain.
Sorry I accidentally deleted my first post with this solution
