I lost all my tabs when Windows 10 updated - please help

Windows 10 updated and I lost all my tabs despite the fact that ‘Continue where you left off’ is selected in settings. I am on Brave Version 0.70.123 Chromium: 78.0.3904.97 (Official Build) (64-bit)
Please can anyone tell me how to recover my lost tabs.
With grateful thanks (PS I am not a techie kind of person so please reply in very plain English that a lay person can understand, thank you.)

To clarify, all I want is to restore all the Brave browser tabs that were open when my PC shut down to update.
