No funds (40 confirmations)

Hey guys, I have sent BTC from electrum wallet to Bisq wallet and when I click on wallet address on Bisq it takes me to mempool space and the funds are visible there but there is nothing visible on Bisq.
Btw I downloaded new Bisq cause I used last time almost year ago and the DAO thing keeps loading and after 5-10min I get Error “Java heap space” and everything is very laggy.

By downloading a new Bisq you mean updated to version 1.5.1 or a new install?
If you just updated, do a spv resync. https://bisq.wiki/Delete_and_resync_SPV_file
