@DekoaSAO WELP, go to history (ctrl + H) and click "Clear browser data" on the left.
Check those boxes and hit clear data.
Mind that you'll have to log back again to all your accounts so be sure to remember the passwords
You may try at fist with just the 'Cached images and files' and if that doesn't help then go for the 'Cookies and other site data' and if that doesn't work then... Brave is pretty good Chrome based browser so I can recommend you to change it xD
