@eleonardb the error log is expected behavior. For example, I’ll share a screenshot of mine below. Without going into detail, most of the errors there aren’t actually errors but is just it showing that it was checking to see if you could view an ad yet and realizing it can’t. So the “error” was it trying to show an ad but it not being allowed to yet.
Anyway, if you haven’t done so yet, to get the best assistance for your issue you will need to create that support ticket. The form has you provide extra details so they can look at your account specifically Again, that’s a Rewards Support Ticket at https://support.brave.com/hc/en-us/requests/new?ticket_form_id=360001302431
Side Note (unrelated to your problem)
There was another update to Brave to 1.79.119 where they patched a vulnerability. You can see more on that at Release Channel 1.79.119. You may wish to run an update.
