How can I delete wallets from Brave?

I have 2 metamask wallets that have been hacked and I want to remove them from Brave. How do I do that?

Also all the wallets I have on Brave had the same error message: Cannot use ‘in’ operator to search for ‘0x8c35e31f61a41f63f7b947d4f8450f9bceebb12b’ in false
What does this mean? I suspect that the wallet I mainly use has not been working right for some time.
