Transport to Kurak's dungeon not working

For my challenges, I have one that states I need to defeat Kurak. I’ve put the requite 35 blood crystals in the transporter and can’t get the damn thing to work. Any solution?

Loose weight!

You’re probably over encumbered.

Nope. I’m well under. I’m at 55% weight capacity.

It’s 30… but that doesn’t matter here. Regardless, I noticed that I couldn’t get it to show up at all in single player on PlayStation. Are you in single player, private, or official?
