The chainwork value since block 849138 was mined has exceeded the variable allocation size of 12byte in bitcoinj, and this prevents the whole library from working.

This is a network wide problem that prevents all bisq clients from correctly syncing with the blockchain.  
If you are connecting to your own bitcoin node, you will see the btc network peers change continuously between 0 and 1.

Devs are assessing the issue and evaluating the best course of action.
