Updated Browser from very old version, all BAT dissapeared

Hello there. I recently started using my old 2016 MacBook Pro, which I haven’t used since some point in 2021. I updated the browser through the settings app, but after doing this I can no longer see any BAT in the Rewards tab. Have I lost it all?

Opening the rewards tab now displays the onboarding process - I tried doing this but it still says 0 balance in brave://rewards-internals/.

Hello, the BAT you’re referencing were vBAT and no longer eligible for redemption. You can learn more below. Thank you.
