All of the following steps, assume that you normally wish to have Brave Browser > Shields: UP
With Brave Browser running, in a New Window, go to brave://settings/clearBrowserData
Examine all the settings for all three tabs: Basic / Advanced / On exit
Be certain that those settings are what they should be, for your usage. In time, you will have tested those arrangments, and figured out what you need, there.
Be certain – for tabs Advanced / On exit – to Disable: “Site and Shields Settings”
