Taking an offer - "could not decrypt bytes"

Tried to take an offer (a BSQ Swap), after hitting the “CONFIRM: TAKE OFFER…” button, the log shows the following:

INFO b.c.t.p.b.BsqSwapProtocol: Received ackMessage AckMessage{
uid=…
senderNodeAddress=…
sourceType=TRADE_MESSAGE,
sourceMsgClassName=‘BsqSwapFinalizeTxRequest’,
sourceUid=…
sourceId=…
success=false,
errorMessage=‘An error occurred at task: BuyerAsMakerCreatesAndSignsFinalizedTx
Exception message: Could not decrypt bytes
}

Wallet looks ok, and no BTCs are removed. But looks stuck in the “TAKE OFFER” screen. Tried restarting UI, but same result.
