Maker tx failed to broadcast. Your trade has failed because there’s no deposit tx so it can’t continue. As you were the maker, there’s no need for trading fee reimbursement.
To make the funds displayed as locked available again, you have to re-import the seed into your Bisq wallet. First, make sure you have a backup of the current Bisq directory. Failed trade - locked fund - #10 by huey
Version 1.5.2, which is at pre-release, should fix this issue. Release v1.5.2 · bisq-network/bisq · GitHub
