Need some help with some funds locked in a wallet

Hi! I´m trying to solve an issue that makes some funds I have in a wallet inoperable. This wallet is the wallet used by the Brave navigator (BAT). I´d be grateful if anybody could help me with that...
Here is the brave forus link explaining the issue details:
