An error occurred at task

I’ve had no problems trading with BISQ since before 1.3.1. Today I tried to purchase bitcoin and after the offer was accepted got the following error:

An error occurred at task: BuyerVerifiesPreparedDelayedPayoutTx
Donation address is invalid.

I had a look through this website for solutions but its not clear, what do I have to do? This is the biggest trade I’ve done through BISQ and it’s backfired.

Also the “get support” button on the trade doesnt work.
