I got closed a bank account with an incoming payment

As titled, according to the user, the payment has been already made

But the account is closed, so it should come back

What can I do in the meanwhile?

Your account is closed? Well, my guess the other party will raise arbitration if he doesn’t receive money back promptly and you may lose some/all of deposit for listed a dead/closed bank account. Not sure.

Only thing you could do in Bisq is open a dispute with cmd+o if you want.
You might however just wait for the max trade period to run out and open a dispute then if it doesn’t successfully complete.
