As you can see this was the same issue I had. I just went and did the other quest goal and the quest did advance, skipping the casagrada bit.

I've also got a bug on this. I reside varano and did some other stuff, triggering the attack on for. I'd anyway wiped out the steel garrote behind the waterfall. Casagrada spawns but won't enter dialog. He just says color commentary when you click chat. I tried reloading and restarting. Playing on Xbox series x.
