Error: device limit reached - stolen tablet

can’t verify my account on the tablet.

so far using one account on my laptop
one on my phone
one on my old laptop that I did not use for over a year.
and the 4th one should be the laptop I’m trying to verify.

actually just realised I had my tablet stolen 6 months ago with brave on it.
What I should do now?
