Issue wit oasis.app can someone help me?

Basically yesterday I was following step by step the lecture of maker Dao and I just get in the borrow section and then I scan my coinbase wallet to the system, istantely all my eth just disappear. I haven’t create any vault and I haven’t put any collateral yet. It seemed very odd. Can be some kind of hack or bug in the system?

I leave the transaction that I tracked on etherscan:

Does something similar happen to anyone? Do you think there is a chance to get back my balance?

BTW I had some ERC20 tokens too and they are still in the wallet.
